2c=5d
The equation is in standard form.
\frac{2c}{2}=\frac{5d}{2}
Divide both sides by 2.
c=\frac{5d}{2}
Dividing by 2 undoes the multiplication by 2.
5d=2c
Swap sides so that all variable terms are on the left hand side.
\frac{5d}{5}=\frac{2c}{5}
Divide both sides by 5.
d=\frac{2c}{5}
Dividing by 5 undoes the multiplication by 5.
