14x-2x-15=x-2\left(1+x\right)
To find the opposite of 2x+15, find the opposite of each term.
12x-15=x-2\left(1+x\right)
Combine 14x and -2x to get 12x.
12x-15=x-2-2x
Use the distributive property to multiply -2 by 1+x.
12x-15=-x-2
Combine x and -2x to get -x.
12x-15+x=-2
Add x to both sides.
13x-15=-2
Combine 12x and x to get 13x.
13x=-2+15
Add 15 to both sides.
13x=13
Add -2 and 15 to get 13.
x=\frac{13}{13}
Divide both sides by 13.
x=1
Divide 13 by 13 to get 1.
