Question

how do you solve 12=-4(-6x-3)

Answer 1

12=-4(-6x-3)
-4(-6x-3)=12
-(-6x-3)=3
6x+3=3
6x=0
x=0

Answer 2

You first solve the parenthesis towards the right side of the '='

This will give you your first step, i.e.
1) 12 = (-4*-6x) - (3*-4) [remember that two negatives multiplied give a positive]
2) 12 = 24x +12 [you now move the '12' on the right side to the left side of the equation]
3] 12 -12 = 24x
4) 0 = 24x

x= 0 Answer
