x+12=2\left(x-3\right)
Variable x cannot be equal to 3 since division by zero is not defined. Multiply both sides of the equation by x-3.
x+12=2x-6
Use the distributive property to multiply 2 by x-3.
x+12-2x=-6
Subtract 2x from both sides.
-x+12=-6
Combine x and -2x to get -x.
-x=-6-12
Subtract 12 from both sides.
-x=-18
Subtract 12 from -6 to get -18.
x=18
Multiply both sides by -1.
