    Answer:x=150

    Step-by-step explanation:

    Step 1: Subtract 1.2x from both sides.

    0.8x+20-1.2x=1.2x-40-1.2x

    -0.4x+20=-40

    Step 2: Subtract 20 from both sides.

    -0.4x+20-20=-40-20

    -0.4x=-60

    Step 3: Divide both sides by - 0.4.

    -0.4x

    -0.4

    =

    -60

    -0.4
