Question

-5(1-5x)+5(-8x-2)=-4x-8x the answer i got was x=5 , is it right ? How can i plug it back into the equation to show its right? if its wrong please tell me where i went wrong.

Answer 1

Proof

Explanation:

`-5 + 25x - 40x -10 = -4x -8x`

After getting rid of parenthesis

`-15 = -12x -25x +40x`

`-15 = 40x - 37 x`

`-15 = 3x`

`-15/3 = -5 = x`

Your answer is `x=-5`
