    x=-1

    Step-by-step explanation:

    3 (x+5) = 12

    Step 1: Simplify both sides of the equation.

    3 (x+5) = 12

    (3) (x) + (3) (5) = 12 (Distribute)

    3x+15=12

    Step 2: Subtract 15 from both sides.

    3x+15-15=12-15

    3x=-3

    Step 3: Divide both sides by 3.

    3x

    3

    =

    -3

    3

    x=-1

    x = - 1

    Step-by-step explanation:

    3 (x+5) = 12

    Divide each side by 3

    3/3 (x+5) = 12/3

    x+5 = 4

    Subtract 5 from each side

    x+5-5 = 4-5

    x = - 1
