fy=100
Add -500 and 600 to get 100.
yf=100
The equation is in standard form.
\frac{yf}{y}=\frac{100}{y}
Divide both sides by y.
f=\frac{100}{y}
Dividing by y undoes the multiplication by y.
fy=100
Add -500 and 600 to get 100.
\frac{fy}{f}=\frac{100}{f}
Divide both sides by f.
y=\frac{100}{f}
Dividing by f undoes the multiplication by f.
