-g-t=-13+13
Add 13 to both sides.
-g-t=0
Add -13 and 13 to get 0.
-g=t
Add t to both sides. Anything plus zero gives itself.
\frac{-g}{-1}=\frac{t}{-1}
Divide both sides by -1.
g=\frac{t}{-1}
Dividing by -1 undoes the multiplication by -1.
g=-t
Divide t by -1.
-g-t=-13+13
Add 13 to both sides.
-g-t=0
Add -13 and 13 to get 0.
-t=g
Add g to both sides. Anything plus zero gives itself.
\frac{-t}{-1}=\frac{g}{-1}
Divide both sides by -1.
t=\frac{g}{-1}
Dividing by -1 undoes the multiplication by -1.
t=-g
Divide g by -1.
