    x = 6

    Step-by-step explanation:

    You add 18 to both sides so that the equation turns into 12x = 4x + 48

    Then you subtract 4x from both sides so that the equation becomes 8x = 48

    Then you divide both sides by 8 and get x = 6

    Answer : x=6

    Step-by-step explanation:

    Let's solve your equation step-by-step.

    12x-18=4x+30

    Step 1: Subtract 4x from both sides.

    12x-18-4x=4x+30-4x

    8x-18=30

    Step 2: Add 18 to both sides.

    8x-18+18=30+18

    8x=48

    Step 3: Divide both sides by 8.

    8x

    8

    =

    48

    8

    x=6
