\frac{\frac{2\left(u-8\right)}{u-8}-\frac{2}{u-8}}{1-\frac{u-5}{4u-32}}
To add or subtract expressions, expand them to make their denominators the same. Multiply 2 times \frac{u-8}{u-8}.
\frac{\frac{2\left(u-8\right)-2}{u-8}}{1-\frac{u-5}{4u-32}}
Since \frac{2\left(u-8\right)}{u-8} and \frac{2}{u-8} have the same denominator, subtract them by subtracting their numerators.
\frac{\frac{2u-16-2}{u-8}}{1-\frac{u-5}{4u-32}}
Do the multiplications in 2\left(u-8\right)-2.
\frac{\frac{2u-18}{u-8}}{1-\frac{u-5}{4u-32}}
Combine like terms in 2u-16-2.
\frac{\frac{2u-18}{u-8}}{1-\frac{u-5}{4\left(u-8\right)}}
Factor 4u-32.
\frac{\frac{2u-18}{u-8}}{\frac{4\left(u-8\right)}{4\left(u-8\right)}-\frac{u-5}{4\left(u-8\right)}}
To add or subtract expressions, expand them to make their denominators the same. Multiply 1 times \frac{4\left(u-8\right)}{4\left(u-8\right)}.
\frac{\frac{2u-18}{u-8}}{\frac{4\left(u-8\right)-\left(u-5\right)}{4\left(u-8\right)}}
Since \frac{4\left(u-8\right)}{4\left(u-8\right)} and \frac{u-5}{4\left(u-8\right)} have the same denominator, subtract them by subtracting their numerators.
\frac{\frac{2u-18}{u-8}}{\frac{4u-32-u+5}{4\left(u-8\right)}}
Do the multiplications in 4\left(u-8\right)-\left(u-5\right).
\frac{\frac{2u-18}{u-8}}{\frac{3u-27}{4\left(u-8\right)}}
Combine like terms in 4u-32-u+5.
\frac{\left(2u-18\right)\times 4\left(u-8\right)}{\left(u-8\right)\left(3u-27\right)}
Divide \frac{2u-18}{u-8} by \frac{3u-27}{4\left(u-8\right)} by multiplying \frac{2u-18}{u-8} by the reciprocal of \frac{3u-27}{4\left(u-8\right)}.
\frac{4\left(2u-18\right)}{3u-27}
Cancel out u-8 in both numerator and denominator.
\frac{2\times 4\left(u-9\right)}{3\left(u-9\right)}
Factor the expressions that are not already factored.
\frac{2\times 4}{3}
Cancel out u-9 in both numerator and denominator.
\frac{8}{3}
Multiply 2 and 4 to get 8.
