15x-10=6x-x-2-x+3
To find the opposite of x+2, find the opposite of each term.
15x-10=5x-2-x+3
Combine 6x and -x to get 5x.
15x-10=5x+1-x
Add -2 and 3 to get 1.
15x-10-5x=1-x
Subtract 5x from both sides.
10x-10=1-x
Combine 15x and -5x to get 10x.
10x-10+x=1
Add x to both sides.
11x-10=1
Combine 10x and x to get 11x.
11x=1+10
Add 10 to both sides.
11x=11
Add 1 and 10 to get 11.
x=\frac{11}{11}
Divide both sides by 11.
x=1
Divide 11 by 11 to get 1.
