WEBTo Solve a System of Equations by Elimination. Write both equations in standard form. If any coefficients are fractions, clear them. Make the coefficients of one variable opposites. Decide which variable you will eliminate. Multiply one or both equations so that the coefficients of that variable are opposites.

WEBThe elimination method is a technique for solving systems of linear equations. Let's walk through a couple of examples. Example 1. We're asked to solve this system of equations: 2 y + 7 x = − 5 5 y − 7 x = 12. We notice that the first equation has a 7 x term and the second equation has a − 7 x term.

WEBThe basic idea is if you have 2 equations, you can sometimes do a single operation and then add the 2 equations in a way that eleiminates 1 of the 2 variables as the example that follows shows. In this system, if we add the 2 equations together, the $$ \red{- 10y} $$ and $$ \red{10y} $$ will eliminate each other!
