2x+x+12+3x-9=117
Combine x and x to get 2x.
3x+12+3x-9=117
Combine 2x and x to get 3x.
6x+12-9=117
Combine 3x and 3x to get 6x.
6x+3=117
Subtract 9 from 12 to get 3.
6x=117-3
Subtract 3 from both sides.
6x=114
Subtract 3 from 117 to get 114.
x=\frac{114}{6}
Divide both sides by 6.
x=19
Divide 114 by 6 to get 19.
