    X=3

    Explanation:

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

    2x-5 (x-4) = -9+4x+8

    Step 1: Simplify both sides of the equation.

    2x-5 (x-4) = -9+4x+8

    2x + (-5) (x) + (-5) (-4) = -9+4x+8 (Distribute)

    2x+-5x+20=-9+4x+8

    (2x+-5x) + (20) = (4x) + (-9+8) (Combine Like Terms)

    -3x+20=4x+-1

    -3x+20=4x-1

    Step 2: Subtract 4x from both sides.

    -3x+20-4x=4x-1-4x

    -7x+20=-1

    Step 3: Subtract 20 from both sides.

    -7x+20-20=-1-20

    -7x=-21

    Step 4: Divide both sides by - 7.

    -7x

    -7

    =

    -21

    -7

    x=3

    Answer:

    x=3
