1. The simplified expression is 10x+8y-12.

Combine like terms to simplify the expression.

-6x-12+8y+16x

-6x and 16x are both like terms, so those can be combined.

-6x+16x=10x

10x+8y-12

2. The solution to the equation is x=13.

Solve by adding 17 to both sides of the equation.

-4=-17+x

-4+17=-17+17+x

13=x
