190+8x-2+10x+10=360
Add 120 and 70 to get 190.
188+8x+10x+10=360
Subtract 2 from 190 to get 188.
188+18x+10=360
Combine 8x and 10x to get 18x.
198+18x=360
Add 188 and 10 to get 198.
18x=360-198
Subtract 198 from both sides.
18x=162
Subtract 198 from 360 to get 162.
x=\frac{162}{18}
Divide both sides by 18.
x=9
Divide 162 by 18 to get 9.
