-D+F=-2-E
Subtract E from both sides.
-D=-2-E-F
Subtract F from both sides.
-D=-E-F-2
The equation is in standard form.
\frac{-D}{-1}=\frac{-E-F-2}{-1}
Divide both sides by -1.
D=\frac{-E-F-2}{-1}
Dividing by -1 undoes the multiplication by -1.
D=E+F+2
Divide -2-E-F by -1.
E+F=-2+D
Add D to both sides.
E=-2+D-F
Subtract F from both sides.
