    3.

    2x - 4 = 10

    Add 4 to both sides.

    2x = 14

    Divide both sides by 2.

    x = 7

    4.

    3 (x/2) = x/4

    Distributive property.

    3x/2 = x/4

    Convert denominators to a common number.

    6x/4 = x/4

    Multiply both sides by 4.

    6x = x

    Subtract x from both sides.

    5x = 0

    Divide both sides by 5.

    x = 0

    This equation is equal to 0.

    5.

    3 (n + 2) = n - 5

    Distributive property.

    3n + 6 = n - 5

    Subtract n from both sides.

    2n + 6 = - 5

    Subtract 6 from both sides.

    2n = - 11

    Divide both sides by 2.

    n = - 5.5
