x=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.
x=3x+6
Use the distributive property to multiply 3 by x+2.
x-3x=6
Subtract 3x from both sides.
-2x=6
Combine x and -3x to get -2x.
x=\frac{6}{-2}
Divide both sides by -2.
x=-3
Divide 6 by -2 to get -3.
