    Solve 2/3(2X-4) = 1/2(X+3)-4

    I did everything I could to try and solve this and I cannot get the correct answer. I feel like an absolute idiot. Could anybody please break down these steps for me so I could get the correct answer:

    2/3(2X-4) = 1/2(X+3)-4

    Thank you so much!

    Is it this? \frac{2}{3}\cdot (2x-4) = \frac{1}{2}\cdot (x+3) - 4

    If so, you may just want to multiply the world by 6.

    4\cdot (2x-4) = 3\cdot (x+3) - 24

    That looks WAY easier.
