    x=7/2

    Step-by-step explanation:

    First, distribute the 9 on the left side

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

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

    27-18x = 2 (10-8x)

    Next, distribute the 2 on the right side

    27-18x = (2*10) + (2*-8x)

    27-18x=20-16x

    Now, move all the numbers to one side of the equation, and the variables to the other.

    27-18x=20-16x

    Add 18x to both sides

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

    27=20+2x

    Subtract 20 from both sides

    27-20=20-20+2x

    7=2x

    Now all the variables are on one side, and the numbers are on the other. x is still not by itself. It is being multiplied by 2. To undo this, divide both sides by 2

    7/2=2x/2

    7/2=x
