9x+42=100-9x-22
Combine 11x and -2x to get 9x.
9x+42=78-9x
Subtract 22 from 100 to get 78.
9x+42+9x=78
Add 9x to both sides.
18x+42=78
Combine 9x and 9x to get 18x.
18x=78-42
Subtract 42 from both sides.
18x=36
Subtract 42 from 78 to get 36.
x=\frac{36}{18}
Divide both sides by 18.
x=2
Divide 36 by 18 to get 2.
