12=3\left(x+2\right)
Variable x cannot be equal to -2 since division by zero is not defined. Multiply both sides of the equation by x+2.
12=3x+6
Use the distributive property to multiply 3 by x+2.
3x+6=12
Swap sides so that all variable terms are on the left hand side.
3x=12-6
Subtract 6 from both sides.
3x=6
Subtract 6 from 12 to get 6.
x=\frac{6}{3}
Divide both sides by 3.
x=2
Divide 6 by 3 to get 2.
