7x+30=84+x+2x
Combine 3x and 4x to get 7x.
7x+30=84+3x
Combine x and 2x to get 3x.
7x+30-3x=84
Subtract 3x from both sides.
4x+30=84
Combine 7x and -3x to get 4x.
4x=84-30
Subtract 30 from both sides.
4x=54
Subtract 30 from 84 to get 54.
x=\frac{54}{4}
Divide both sides by 4.
x=\frac{27}{2}
Reduce the fraction \frac{54}{4} to lowest terms by extracting and canceling out 2.
