    \[\frac{9}{x}+2=-\frac{4}{5}\] We notice that in the denominator there is x and 5. So we multiply 5x to both the sides \[5x \times (\frac{9}{x}+2)=-5x \times \frac{4}{5}\] Can you tell what we'll get now?

    \[5 \cancel{x} \times \frac{9}{\cancel{x}}+ 5x \times 2 = -\cancel{5}x \times \frac{4}{\cancel{5}}\]

    \[40+10x=-4x\]Subtract 10x from both sides \[40=-14x\]\[x= \frac{-40}{14}\]
