This question is really asking you to find the value of x. Once you have found the x value you can prove or disprove the equation. To solve for x, isolate it in the equation.
3x + 12 = 5x +4 (Subtract 4 from both sides)
3x + 8 = 5x (Subtract 3x from both sides)
8 = 2x (divide both sides by 2)
4 = x So, if x = 4 does that prove your equation is correct?
3(4) + 12 = 24 5(4) + 4 = 24
