\frac{685}{33}+\left(x-1\right)\left(-\frac{83}{33}\right)=13
Fraction \frac{-83}{33} can be rewritten as -\frac{83}{33} by extracting the negative sign.
\frac{685}{33}+x\left(-\frac{83}{33}\right)-\left(-\frac{83}{33}\right)=13
Use the distributive property to multiply x-1 by -\frac{83}{33}.
\frac{685}{33}+x\left(-\frac{83}{33}\right)+\frac{83}{33}=13
Multiply -1 and -\frac{83}{33} to get \frac{83}{33}.
\frac{685+83}{33}+x\left(-\frac{83}{33}\right)=13
Since \frac{685}{33} and \frac{83}{33} have the same denominator, add them by adding their numerators.
\frac{768}{33}+x\left(-\frac{83}{33}\right)=13
Add 685 and 83 to get 768.
\frac{256}{11}+x\left(-\frac{83}{33}\right)=13
Reduce the fraction \frac{768}{33} to lowest terms by extracting and canceling out 3.
x\left(-\frac{83}{33}\right)=13-\frac{256}{11}
Subtract \frac{256}{11} from both sides.
x\left(-\frac{83}{33}\right)=\frac{143}{11}-\frac{256}{11}
Convert 13 to fraction \frac{143}{11}.
x\left(-\frac{83}{33}\right)=\frac{143-256}{11}
Since \frac{143}{11} and \frac{256}{11} have the same denominator, subtract them by subtracting their numerators.
x\left(-\frac{83}{33}\right)=-\frac{113}{11}
Subtract 256 from 143 to get -113.
x=-\frac{113}{11}\left(-\frac{33}{83}\right)
Multiply both sides by -\frac{33}{83}, the reciprocal of -\frac{83}{33}.
x=\frac{-113\left(-33\right)}{11\times 83}
Multiply -\frac{113}{11} times -\frac{33}{83} by multiplying numerator times numerator and denominator times denominator.
x=\frac{3729}{913}
Do the multiplications in the fraction \frac{-113\left(-33\right)}{11\times 83}.
x=\frac{339}{83}
Reduce the fraction \frac{3729}{913} to lowest terms by extracting and canceling out 11.
