Answer: not sure if that is a b but i beleive it is so
bh+hr=25
move all terms to the left side and set equal to 0. then set each factor equal to zero.
h= [tex]\frac{25}{b+r}[/tex]
isolate the variable by dividing each side by factors that dont
contain the variable.
r=[tex]\frac{25}{h}-b[/tex]
x=[tex]\frac{r-h}{y}[/tex]
isolate the variable by dividing each side by factors that dont
contain the variable.
h=-xy+r
solve for r by simplifieng both sides of the equation, then isolating the variable.
r=xy+h
