2dm=t
Swap sides so that all variable terms are on the left hand side.
2md=t
The equation is in standard form.
\frac{2md}{2m}=\frac{t}{2m}
Divide both sides by 2m.
d=\frac{t}{2m}
Dividing by 2m undoes the multiplication by 2m.
2dm=t
Swap sides so that all variable terms are on the left hand side.
\frac{2dm}{2d}=\frac{t}{2d}
Divide both sides by 2d.
m=\frac{t}{2d}
Dividing by 2d undoes the multiplication by 2d.
