\frac{1}{2}x+\frac{4}{3}\left(x+20\right)=34
Reduce the fraction \frac{8}{6} to lowest terms by extracting and canceling out 2.
\frac{1}{2}x+\frac{4}{3}x+\frac{4}{3}\times 20=34
Use the distributive property to multiply \frac{4}{3} by x+20.
\frac{1}{2}x+\frac{4}{3}x+\frac{4\times 20}{3}=34
Express \frac{4}{3}\times 20 as a single fraction.
\frac{1}{2}x+\frac{4}{3}x+\frac{80}{3}=34
Multiply 4 and 20 to get 80.
\frac{11}{6}x+\frac{80}{3}=34
Combine \frac{1}{2}x and \frac{4}{3}x to get \frac{11}{6}x.
\frac{11}{6}x=34-\frac{80}{3}
Subtract \frac{80}{3} from both sides.
\frac{11}{6}x=\frac{102}{3}-\frac{80}{3}
Convert 34 to fraction \frac{102}{3}.
\frac{11}{6}x=\frac{102-80}{3}
Since \frac{102}{3} and \frac{80}{3} have the same denominator, subtract them by subtracting their numerators.
\frac{11}{6}x=\frac{22}{3}
Subtract 80 from 102 to get 22.
x=\frac{22}{3}\times \frac{6}{11}
Multiply both sides by \frac{6}{11}, the reciprocal of \frac{11}{6}.
x=\frac{22\times 6}{3\times 11}
Multiply \frac{22}{3} times \frac{6}{11} by multiplying numerator times numerator and denominator times denominator.
x=\frac{132}{33}
Do the multiplications in the fraction \frac{22\times 6}{3\times 11}.
x=4
Divide 132 by 33 to get 4.
