To combine two equations, add the left sides together, and add the right sides together. If you set your equation up right, one of the variables should cancel. Here's an example using the same equations as the last step: Your equations are 6x - 2y = 6 and -x + 2y = 4.

Combination involves adding the two equations together to eliminate a variable. Often, one or both of the equations must be multiplied by a constant before they are added together.

There are three ways to solve systems of linear equations in two variables: graphing. substitution method. elimination method.

Two or more linear equations that all contain the same unknown variables are called a system of simultaneous linear equations. Solving such a system means finding values for the unknown variables which satisfy all the equations at the same time.
