See a solution process below:

Explanation:

Step 1) Add color(red)(4)4 to each side of the equation to isolate the xx term while keeping the equation balanced:

12x - 4 + color(red)(4) = 32 + color(red)(4)12xโˆ’4+4=32+4

12x - 0 = 3612xโˆ’0=36

12x = 3612x=36

Step 2) Divide each side of the equation by color(red)(12)12 to solve for xx while keeping the equation balanced:

(12x)/color(red)(12) = 36/color(red)(12)12x12=3612

(color(red)(cancel(color(black)(12)))x)/cancel(color(red)(12)) = 3

x = 3
