Know if an ordered pair is a solution to a system of linear equations in two variables or not. Solve a system of linear equations in two variables by graphing. Solve a system of linear equations in two variables by the substitution method. Solve a system of linear equations in two variables by the elimination by addition method.
Now we'll solve some more complicated equations and inequalities - ones that have two-step solutions, because they involve two operations. Remember, solving equations is like solving a puzzle. Just keep working through the steps until you get the variable you're looking for alone on one side of the equation. Here's a two-step equation. Let's start with the variable x, and describe, step by step, what is being done to x in an equation.
