Solve for R E=IR for R

$E = I R$ for $R$

Rewrite the equation as $I R = E$ .

$I R = E$

Divide each term in $I R = E$ by $I$ and simplify.

Divide each term in $I R = E$ by $I$ .

$\frac{I R}{I} = \frac{E}{I}$

Simplify the left side.

Cancel the common factor of $I$ .

Cancel the common factor.

$\frac{I R}{I} = \frac{E}{I}$

Divide $R$ by $1$ .

$R = \frac{E}{I}$
