According to order - of - operations (PEMDAS), we first do the division. So, $9x\div5=\frac{9x}{5}$. The expression becomes $- 9x+\frac{9x}{5}$.

Step2: Find a common denominator

The common denominator of 1 and 5 is 5. Rewrite $-9x$ as $-\frac{45x}{5}$. The expression is now $-\frac{45x}{5}+\frac{9x}{5}$.

Step3: Combine like - terms

$-\frac{45x}{5}+\frac{9x}{5}=\frac{-45x + 9x}{5}=\frac{-36x}{5}=- \frac{36x}{5}$

Answer:

$-\frac{36x}{5}$
