30\left(-4\times \frac{-92}{51}-8\right)=3\left(-6\right)\times \frac{-92}{51}+4
Multiply both sides of the equation by 12, the least common multiple of 2,4,3.
30\left(-4\left(-\frac{92}{51}\right)-8\right)=3\left(-6\right)\times \frac{-92}{51}+4
Fraction \frac{-92}{51} can be rewritten as -\frac{92}{51} by extracting the negative sign.
30\left(\frac{-4\left(-92\right)}{51}-8\right)=3\left(-6\right)\times \frac{-92}{51}+4
Express -4\left(-\frac{92}{51}\right) as a single fraction.
30\left(\frac{368}{51}-8\right)=3\left(-6\right)\times \frac{-92}{51}+4
Multiply -4 and -92 to get 368.
30\left(\frac{368}{51}-\frac{408}{51}\right)=3\left(-6\right)\times \frac{-92}{51}+4
Convert 8 to fraction \frac{408}{51}.
30\times \frac{368-408}{51}=3\left(-6\right)\times \frac{-92}{51}+4
Since \frac{368}{51} and \frac{408}{51} have the same denominator, subtract them by subtracting their numerators.
30\left(-\frac{40}{51}\right)=3\left(-6\right)\times \frac{-92}{51}+4
Subtract 408 from 368 to get -40.
\frac{30\left(-40\right)}{51}=3\left(-6\right)\times \frac{-92}{51}+4
Express 30\left(-\frac{40}{51}\right) as a single fraction.
\frac{-1200}{51}=3\left(-6\right)\times \frac{-92}{51}+4
Multiply 30 and -40 to get -1200.
-\frac{400}{17}=3\left(-6\right)\times \frac{-92}{51}+4
Reduce the fraction \frac{-1200}{51} to lowest terms by extracting and canceling out 3.
-\frac{400}{17}=-18\times \frac{-92}{51}+4
Multiply 3 and -6 to get -18.
-\frac{400}{17}=-18\left(-\frac{92}{51}\right)+4
Fraction \frac{-92}{51} can be rewritten as -\frac{92}{51} by extracting the negative sign.
-\frac{400}{17}=\frac{-18\left(-92\right)}{51}+4
Express -18\left(-\frac{92}{51}\right) as a single fraction.
-\frac{400}{17}=\frac{1656}{51}+4
Multiply -18 and -92 to get 1656.
-\frac{400}{17}=\frac{552}{17}+4
Reduce the fraction \frac{1656}{51} to lowest terms by extracting and canceling out 3.
-\frac{400}{17}=\frac{552}{17}+\frac{68}{17}
Convert 4 to fraction \frac{68}{17}.
-\frac{400}{17}=\frac{552+68}{17}
Since \frac{552}{17} and \frac{68}{17} have the same denominator, add them by adding their numerators.
-\frac{400}{17}=\frac{620}{17}
Add 552 and 68 to get 620.
\text{false}
Compare -\frac{400}{17} and \frac{620}{17}.
