23x-15x-10=2x+2
Use the distributive property to multiply -5 by 3x+2.
8x-10=2x+2
Combine 23x and -15x to get 8x.
8x-10-2x=2
Subtract 2x from both sides.
6x-10=2
Combine 8x and -2x to get 6x.
6x=2+10
Add 10 to both sides.
6x=12
Add 2 and 10 to get 12.
x=\frac{12}{6}
Divide both sides by 6.
x=2
Divide 12 by 6 to get 2.
