Question

Solve and check.
6[2 - (2x - 4)] = 2(6 - 3x)

Answer 1

3(2-(2x-4))=6-3x
6-6x+12=6-3x
-6x+12=-3x
-3x=-12
x=4

Answer 2

now the checking part:

The left side - using 4 instead of "x":
6(2-(2*4-4)) = 6(2-(4))=-12

The right side - using 4 instead of "x":
2(6-3*4)=2*(6-12)=2*(-6)=-12

both sides are equal -12, so it checks out.
