Answer

x=8x=8

Step-by-step solution

3 steps

  1. Write the given equation.

    3(x−4)=123(x-4)=12

  2. Divide both sides of the equation by 3 to isolate the term (x−4)(x-4).

    3(x−4)3=123\frac{3(x-4)}{3} = \frac{12}{3} x−4=4x-4 = 4

  3. Add 4 to both sides of the equation to solve for xx.

    x−4+4=4+4x-4+4 = 4+4 x=8x = 8

    The solution for xx is:
