The value of x in the equation is 7

Step-by-step explanation:

To find the value of x, we will follow the steps below:

8+4 = 2 (x-1)

open the parenthesis on the right-hand side of the equation by multiply x-1 by the 2

8+4 = 2x - 2

12 = 2x - 2

Add 2 to both-side of the equation

12 + 2 = 2x - 2 + 2

14 = 2x

Divide both-side of the equation by 2

14/2 = 2x/2

7 = x

x = 7

The value of x in the equation is 7
