Question

what value of x will make the equation 5(6x + 8-2x) =-10

Answer 1

5(6x + 8 - 2x) = -10
5(4x + 8) = -10
4x + 8 = -10/5
4x + 8 = -2
4x = -2 - 8
4x = -10
x = -10/4
x = - 5/2

check..
5(6x + 8 - 2x) = -10
5(4x + 8) = -10
5(4(-5/2) + 8) = -10
5(-10 + 8) = -10
5(-2) = -10
-10 = -10 (correct)

if you replace x with -5/2, then the equation will be true
