This document contains the steps to solve a system of equations involving two linear equations: y=5x+11 and y=10x-4. It shows the work of setting the two equations equal to each other and solving for x, finding that x=3. It then substitutes x=3 back into one of the original equations to verify the solution.

1. Y=5x+11
Y=10x-4

2. 5x+11=10x-4
-5x -5x

3. 5x+11=10x-4
-5x -5x
11=5x-4
+4 +4
15=5x
/5 /5
3=x

4. 5x+11
5(3)+11
8+11
