### Expressions and Equations 8.EE.C.8

**8. Analyze and solve pairs of simultaneous linear equations.**

Dealing with linear equations means knowing how to handle two-variable equations. We don't just have *x* anymore. We've added a *y* as well. Why? It makes life interesting. Plus, it's sort of necessary in order to further their mathematical education. Oh yeah, *that*.

But wait. A pair of linear equations means more than one. So your students should know how to deal with *two* different linear equations, each with *two* variables. The goal here is to help your students understand how to handle multiple linear equations and what they mean.

Basically, make sure they don't drown in all the equations and the variables.
