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
