OF-5-2F=-1
Subtract 2F from both sides.
OF-2F=-1+5
Add 5 to both sides.
OF-2F=4
Add -1 and 5 to get 4.
\left(O-2\right)F=4
Combine all terms containing F.
\frac{\left(O-2\right)F}{O-2}=\frac{4}{O-2}
Divide both sides by O-2.
F=\frac{4}{O-2}
Dividing by O-2 undoes the multiplication by O-2.
OF=-1+2F+5
Add 5 to both sides.
OF=4+2F
Add -1 and 5 to get 4.
FO=2F+4
The equation is in standard form.
\frac{FO}{F}=\frac{2F+4}{F}
Divide both sides by F.
O=\frac{2F+4}{F}
Dividing by F undoes the multiplication by F.
O=2+\frac{4}{F}
Divide 4+2F by F.
