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.
We can solve it by using the substitution method. This method can be applied to any other system of linear equations in two variables. What this method involves is solving one equation for one of the variables and plugging this into the other equation to solve. Let's see how it works with our system.
