15-3x-12=12-2\left(x+3\right)
Use the distributive property to multiply -3 by x+4.
3-3x=12-2\left(x+3\right)
Subtract 12 from 15 to get 3.
3-3x=12-2x-6
Use the distributive property to multiply -2 by x+3.
3-3x=6-2x
Subtract 6 from 12 to get 6.
3-3x+2x=6
Add 2x to both sides.
3-x=6
Combine -3x and 2x to get -x.
-x=6-3
Subtract 3 from both sides.
-x=3
Subtract 3 from 6 to get 3.
x=-3
Multiply both sides by -1.
