IR=V
Swap sides so that all variable terms are on the left hand side.
RI=V
The equation is in standard form.
\frac{RI}{R}=\frac{V}{R}
Divide both sides by R.
I=\frac{V}{R}
Dividing by R undoes the multiplication by R.
IR=V
Swap sides so that all variable terms are on the left hand side.
\frac{IR}{I}=\frac{V}{I}
Divide both sides by I.
R=\frac{V}{I}
Dividing by I undoes the multiplication by I.
