Answer:
x = 3
Step-by-step explanation:
Distributive property: a(b + c) = (a*b) + (a*c)
3(2x - 4) = 3x - 3
3*2x - 3*4 = 3x - 3
6x - 12 = 3x - 3 {Add 12 to both sides}
6x -12 + 12 = 3x -3 + 12
6x = 3x + 9 {subtract 3x from both side}
6x - 3x = 3x - 3x + 9
3x = 9 {Divide both sides by 3}
3x/3 = 9/3
x = 3
