You know that we have to simplify the algebra equation, so first you have to combine x and 2x. X + 2x equals to 3x. Now that we combined x and 2x which makes 3x, we have to do 7 and -8. 7 + -8 which equals to -1. Therefore, the answer to this algebra equation is 3x + -1.

X= -7+2x-8
-2x+x= -7-8
-x= -15 then multiply by -1 on both
-1(-x)= -1(-15) sides to get rid of all the x=15 negative on the x and 15
