Answer:
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
