    x = 4

    Step-by-step explanation:

    1.5 (x + 4) - 3 = 4.5 (x - 2)

    Distributive property

    1.5x + 6 - 3 = 4.5x - 9

    1.5x + 3 = 4.5x - 9

    1.5x - 4.5x = - 9 - 3

    -3x = - 12

    x = 4

    Expand

    1.5x + 6 - 3 = 4.5x - 9

    Simplify 1.5x + 6 - 3 to 1.5x + 3

    1.5x + 3 = 4.5x - 9

    Subtract 1.5x from both sideds

    3 = 4.5x - 9 - 1.5x

    Simplify 4.5x - 9 - 1.5x to 3x - 9

    3 = 3x - 9

    Add 9 to both sides

    3 + 9 = 3x

    Simplify 3 + 9 to 12

    12 = 3x

    Divide both sides by 3

    12/3 = x

    Simplify 12/3 to 4

    4 = x

    Switch sides

    x = 4
