Step-by-Step Solution

To solve the equation (x4)3=2(x+6) (x-4)\cdot3=2(x+6) , we'll follow a systematic approach:

Step 1: Apply the distributive property to both sides of the equation.

  • On the left side: 3(x4)=3x12 3(x-4) = 3x - 12
  • On the right side: 2(x+6)=2x+12 2(x+6) = 2x + 12

Step 2: Rewrite the equation with the expanded terms:
3x12=2x+12 3x - 12 = 2x + 12

Step 3: Move all terms involving x x to one side and constant terms to the other.

  • Subtract 2x 2x from both sides to move x x terms to the left:
    3x2x=12+12 3x - 2x = 12 + 12 which simplifies to x12=12 x - 12 = 12 .
  • Add 12 to both sides to isolate x x :
    x=24 x = 24 .

Therefore, the solution to the equation is x=24 x = 24 .
