    Step-by-step explanation:

    9 (3-2x) = 2 (10-8x)

    Step 1: Simplify both sides of the equation.

    9 (3-2x) = 2 (10-8x)

    (9) (3) + (9) (-2x) = (2) (10) + (2) (-8x) (Distribute)

    27+-18x=20+-16x

    -18x+27=-16x+20

    Step 2: Add 16x to both sides.

    -18x+27+16x=-16x+20+16x

    -2x+27=20

    Step 3: Subtract 27 from both sides.

    -2x+27-27=20-27

    -2x=-7

    Step 4: Divide both sides by - 2.

    -2x - 2 = - 7 / -2

    x = 7 / 2

    Answer:

    x = 7 / 2
