Add the like terms first.

Explanation:

So 10x10x and xx are like terms having the same variable, so when adding them, you get

10x + x = 11x10x+x=11x

Then add up the rest and put them in the expression.

-8-7 = -15−8−7=−15

So having 11x11x and -15−15, you have simplified it. The final answer is

11x-1511x−15
