Answer:
[tex]h=\frac{25}{(b+r)}[/tex]
Step-by-step explanation:
We have the equation [tex]bh+hr=25[/tex]. Solve the equation for h means that we have to clear h.
Then first thing we can do is use common factor h.
[tex]b.h+h.r=25\\h(b+r)=25[/tex]
Now, for the last step, we have to divide both sides of the equation in (b+r)
[tex]h(b+r)=25\\\\\frac{h(b+r)}{(b+r)} =\frac{25}{(b+r)} \\\\h=\frac{25}{(b+r)}[/tex]
