Question

-5(1 - 5x) + 5(-8x - 2) = -4x - 8x
I got x = -5, but I don't feel like it's correct. Help?

Answer 1

x = -5 is the correct answer

Answer 2

Check:

-5(1 - 5x) + 5(-8x - 2) = -4x - 8x

-5(1 - 5(-5)) + 5(-8(-5) - 2) = -4(-5) - 8(-5)

-5(1 +25) + 5(40 - 2) = 20 + 40

-5(26) + 5(38) = 20 + 40

-130 + 190 = 20 + 40

60 = 60

So the answer checks out
