- Right away we see that expressions (a), (b), and (d) are equivalent, since addition is commutative: $2x + 8 = 8 + 2x$. We now only have to check (c) and (e). If $x=0$, (c) and (e) have the value 4, whereas (a), (b), and (d) have the value 8.So (c) and (e) are not equivalent to (a), (b), and (d).Moreover, if $x=1$, then (c) has the value 6 and (e) has the value 5, so those two expressions are not equivalent either.For (c), we can use the distributive property and decompose one of the numbers to write two equivalent expressions: $$ \begin{align} &2x+4 \\ &2(x+2) \\ &2(x+1+1) \end{align} $$.o (c) and (e) are not equivalent to (a), (b), and (d). Moreover, if $x=1$, then (c) has the value 6 and (e) has the value 5, so those two expressions are not equivalent either. For (c), we can use the distributive property and decompose one of the numbers to write two equivalent expressions:

- 1 multiply all terms in the first equation by 2. 8x - 2y = 16. -8x + 2y = -5. 2  add the two equations. 0x + 0y = 11 or 0 = 11.  Conclusion: Because there are no values of x and y for which 0x + 0y = 11, the given system of equations has no solutions. This system is inconsistent.

- 3x - 7 = 2. This is an EQUATION, because it has a left side, a right side, and an = sign separating the two. 3x - 7. This is an EXPRESSION, because there are no sides and no = sign.

Properties of equalities Properties of equalities. Two equations that have the same solution are called equivalent equations e.g. 5 +3 = 2 + 6. And this as we learned in a previous section is shown by the equality sign =. An inverse operation are two operations that undo each other e.g. addition and subtraction or multiplication and division. You can perform the same inverse operation on each side of an equivalent equation without changing the equality.

WHAT IS 2 5/8 DIVIDED BY 3 3/4? IN FRACTION FORM PLEASE!? Report Abuse. 7/10 becuz: 1) 2 5/8 divided by 3 3/4 is equal to 21/8 divided by 15/4. 2)then, you would use the reciprocal of 15/4 by switching the fraction around to 4/15. 3)After u do that, u would change the division sin to a multiplication sign and get the equation 21/8 times 4/15. 5/8 divided by 3 3/4 is 7/10 2+5/8 = 16/8 + 5/8 = 21/8 and 3+3/4 = 12/4 + 3/4 = 15/4 21/8 divided by 15/4 21/8....... 21/8 * 4/15 .... 21/8 * 8/30 ------ = --------------- = ----------------- = 21/30 = 7/10 15/4 ..... 15/4 * 4/15 .... 1.

How to Convert Units of Measurement In the expression 3 x + 7, 7 is a constant. A number that is in a term all by itself. In the expression y = 2 x – 16, 16 is a constant. A term that is just a number, not multiplied by a variable or anything else. It's just along for the ride.

Understanding Equivalent Fractions The best way to think about equivalent fractions is that they are fractions that have the same overall value. For example, if we cut a pie exactly down the middle, into two equally sized pieces, one piece is the same as one half of the pie.nd yes grasshopper, 2/4 is an equivalent fraction for 4/8 too.As you already know, we are nuts about rules. So, let’s look at the Rule to check to see if two fractions are equivalent or equal. The rule for equivalent fractions can be a little tough to explain, but hang in there, we will clear things up in just a bit.

Expression (mathematics) The evaluation of an expression is dependent on the definition of the mathematical operators and on the system of values that is its context. Two expressions are said to be equivalent if, for each combination of values for the free variables, they have the same output, i.e., they represent the same function.

What is the difference between an Expression and an Equation? The only way that you solve this expression is that you need to know what the variables represent. It can be as simple as 8x - 2 or as complicated as 5x(x + 2y) - (5x + 2y) + y(2x + z). In either of these expressions all you have to do is define the variables and using PEMDAS simplify and solve the problem.

What's the difference between an expression and an equation? 2(2+x)=8 equations. Think like a see-saw, and the = is the balancing point. The two sides must come out to the same quantity. An expression is only one side, or part of one side, of the see-saw; an equation is showing both sides of the see-saw in balance.

- For functions of three variables, the equivalent of x!awill be (x;y;z) !(a;b;c), and so on. This has a very important consequence, one which makes computing limits for functions of several variables more di¢ cult. While xcould only approach afrom two directions, from the left or from the right, (x;y) can approach (a;b) from in–nitely many directions.

- The calculator can only handle functions. For example, 2y + 3x = 6 is a function, because you can solve for y: 2y + 3x = 6 2y = –3x + 6 y = (–3/2)x + 3. On the other hand, y 2 + 3x = 6 is not a function, because you can not solve for a unique y: I mean, yes, this is solved for y =, but it's not unique.

Identifying Equivalent Expressions However, to show that expressions are equivalent requires using definitions and properties. Show the student a pair of expressions such as 2 x and 3 x or 2 x and. Evaluate the pairs of expressions for a particular value for which they are equal (e.g., x = 0 and x = 2, respectively). Then evaluate the pairs of expressions for another value to show that they are not always equal and are not, therefore, equivalent.
