Brittanyleann_2 Group Title solve: (9/x)+2=-4/5 2 years ago 2 years ago

$\frac{9}{x}+2=-\frac{4}{5}$ 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?

2. Brittanyleann_2 Group Title

this is where im having problems do the x's cancel out?

3. ash2326 Group Title

Yes they cancel out

You get 40+10x = -4x

$5x \times \frac{9}{x}+ 5x \times 2 = -5x \times \frac{4}{5}$

7. Brittanyleann_2 Group Title

40/-14 is what i got but thats incorrect

8. sasogeek Group Title

40?

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

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

Now you can simplify the answer
