be^{2}=f+23-50
Subtract 50 from both sides.
be^{2}=f-27
Subtract 50 from 23 to get -27.
e^{2}b=f-27
The equation is in standard form.
\frac{e^{2}b}{e^{2}}=\frac{f-27}{e^{2}}
Divide both sides by e^{2}.
b=\frac{f-27}{e^{2}}
Dividing by e^{2} undoes the multiplication by e^{2}.
f+23=be^{2}+50
Swap sides so that all variable terms are on the left hand side.
f=be^{2}+50-23
Subtract 23 from both sides.
f=be^{2}+27
Subtract 23 from 50 to get 27.
