\frac{4\times 17+6}{17}=\frac{5}{17}x\times \frac{4\times 8+5}{8}
Variable x cannot be equal to 0 since division by zero is not defined. Multiply both sides of the equation by x.
\frac{68+6}{17}=\frac{5}{17}x\times \frac{4\times 8+5}{8}
Multiply 4 and 17 to get 68.
\frac{74}{17}=\frac{5}{17}x\times \frac{4\times 8+5}{8}
Add 68 and 6 to get 74.
\frac{74}{17}=\frac{5}{17}x\times \frac{32+5}{8}
Multiply 4 and 8 to get 32.
\frac{74}{17}=\frac{5}{17}x\times \frac{37}{8}
Add 32 and 5 to get 37.
\frac{74}{17}=\frac{5\times 37}{17\times 8}x
Multiply \frac{5}{17} times \frac{37}{8} by multiplying numerator times numerator and denominator times denominator.
\frac{74}{17}=\frac{185}{136}x
Do the multiplications in the fraction \frac{5\times 37}{17\times 8}.
\frac{185}{136}x=\frac{74}{17}
Swap sides so that all variable terms are on the left hand side.
x=\frac{74}{17}\times \frac{136}{185}
Multiply both sides by \frac{136}{185}, the reciprocal of \frac{185}{136}.
x=\frac{74\times 136}{17\times 185}
Multiply \frac{74}{17} times \frac{136}{185} by multiplying numerator times numerator and denominator times denominator.
x=\frac{10064}{3145}
Do the multiplications in the fraction \frac{74\times 136}{17\times 185}.
x=\frac{16}{5}
Reduce the fraction \frac{10064}{3145} to lowest terms by extracting and canceling out 629.
