-b=m
Add m to both sides. Anything plus zero gives itself.
\frac{-b}{-1}=\frac{m}{-1}
Divide both sides by -1.
b=\frac{m}{-1}
Dividing by -1 undoes the multiplication by -1.
b=-m
Divide m by -1.
-m=b
Add b to both sides. Anything plus zero gives itself.
\frac{-m}{-1}=\frac{b}{-1}
Divide both sides by -1.
m=\frac{b}{-1}
Dividing by -1 undoes the multiplication by -1.
m=-b
Divide b by -1.
