Answer:
[tex]x = \frac{5h-9}{r}[/tex]
Step-by-step explanation:
Start by multiplying both sides by 5 to get rid of the fraction
[tex]5* (\frac{rx+9}{5}) = h *5[/tex]
Now you have
[tex]rx+9 = 5h[/tex]
subtract 9 from both sides
[tex]rx+9-9 = 5h-9[/tex]
[tex]rx=5h-9[/tex]
Now divide both sides by r to get x by itself
[tex]\frac{1}{r} * rx = (5h-9)* \frac{1}{r}[/tex]
[tex]x = \frac{5h-9}{r}[/tex]
