We have two algebraic equations and we are trying to find what a and b can equal to fit for both situations. 

1. 6a + b = 16

2. 5a - 2b = 19

The easiest method...

This is simplified by solving common terms (the x's and the y's). Where X and Y terms can't be solved together.

Splitting it up:  

You can see 2x-x= x
