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

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
