Answer
Does not make sense.
Work Step by Step
The given expression is
$\Rightarrow \frac{3-\frac{6}{x+5}}{1+\frac{7}{x-4}}$
Multiply the numerator and the denominator by $(x-4)(x+5)$.
$\Rightarrow \frac{(x-4)(x+5)\left ( 3-\frac{6}{x+5}\right )}{(x-4)(x+5)\left (1+\frac{7}{x-4}\right )}$
Use the distributive property.
$\Rightarrow \frac{3(x-4)(x+5)-\frac{6(x-4)(x+5)}{x+5}}{1(x-4)(x+5)+\frac{7(x-4)(x+5)}{x-4}}$
Cancel common terms.
$\Rightarrow \frac{3(x-4)(x+5)-6(x-4)}{1(x-4)(x+5)+7(x+5)}$
Hence, the given statement does not make sense.
