    Answer:

    6

    Step-by-step explanation:

    3x+12=36−x

    Step 1: Simplify both sides of the equation.

    3x+12=36−x

    3x+12=36+−x

    3x+12=−x+36

    Step 2: Add x to both sides.

    3x+12+x=−x+36+x

    4x+12=36

    Step 3: Subtract 12 from both sides.

    4x+12−12=36−12

    4x=24

    Step 4: Divide both sides by 4.

    4x/4 = 24/4

    x=6

    Answer:

    x=6
