5\times \frac{3x}{6}\times \frac{2}{5}=962.5x-55\times 3^{2}
Multiply both sides of the equation by 55, the least common multiple of 11,5.
5\times \frac{1}{2}x\times \frac{2}{5}=962.5x-55\times 3^{2}
Divide 3x by 6 to get \frac{1}{2}x.
\frac{5}{2}x\times \frac{2}{5}=962.5x-55\times 3^{2}
Multiply 5 and \frac{1}{2} to get \frac{5}{2}.
x=962.5x-55\times 3^{2}
Cancel out \frac{5}{2} and its reciprocal \frac{2}{5}.
x=962.5x-55\times 9
Calculate 3 to the power of 2 and get 9.
x=962.5x-495
Multiply 55 and 9 to get 495.
x-962.5x=-495
Subtract 962.5x from both sides.
-961.5x=-495
Combine x and -962.5x to get -961.5x.
x=\frac{-495}{-961.5}
Divide both sides by -961.5.
x=\frac{-4950}{-9615}
Expand \frac{-495}{-961.5} by multiplying both numerator and the denominator by 10.
x=\frac{330}{641}
Reduce the fraction \frac{-4950}{-9615} to lowest terms by extracting and canceling out -15.
