2x-\left(-x\right)+15+x=-x
Add x to both sides.
2x-\left(-x\right)+15+x+x=0
Add x to both sides.
2x-\left(-x\right)+15+2x=0
Combine x and x to get 2x.
2x-\left(-x\right)+2x=-15
Subtract 15 from both sides. Anything subtracted from zero gives its negation.
2x+x+2x=-15
Multiply -1 and -1 to get 1.
3x+2x=-15
Combine 2x and x to get 3x.
5x=-15
Combine 3x and 2x to get 5x.
x=\frac{-15}{5}
Divide both sides by 5.
x=-3
Divide -15 by 5 to get -3.
