In this lesson, we reviewed strategies for solving systems of linear equations, including using tables, graphs, and algebra. We examined two different algebraic methods, both of which involve substitution of expressions for variables. These methods work with systems of linear equations that are linear functions, as well as ... 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. These terms will cancel if we add the equations together—that is, we'll eliminate the x terms: 2 y + 7 x = − 5 + 5 y − 7 x = 12 7 y + 0 = 7.
