Solve for I P=(R-I)/L

$P = \frac{R - I}{L}$

Rewrite the equation as $\frac{R - I}{L} = P$ .

$\frac{R - I}{L} = P$

Multiply both sides by $L$ .

$\frac{R - I}{L} L = P L$

Simplify the left side.

Simplify $\frac{R - I}{L} L$ .

Cancel the common factor of $L$ .

Cancel the common factor.

$\frac{R - I}{L} L = P L$

Rewrite the expression.

$R - I = P L$

Reorder $R$ and $- I$ .

$- I + R = P L$

Solve for $I$ .

Subtract $R$ from both sides of the equation.

$- I = P L - R$

Divide each term in $- I = P L - R$ by $- 1$ and simplify.

Divide each term in $- I = P L - R$ by $- 1$ .

$\frac{- I}{- 1} = \frac{P L}{- 1} + \frac{- R}{- 1}$

Simplify the left side.

Dividing two negative values results in a positive value.

$\frac{I}{1} = \frac{P L}{- 1} + \frac{- R}{- 1}$

Divide $I$ by $1$ .

$I = \frac{P L}{- 1} + \frac{- R}{- 1}$

Simplify the right side.

Simplify each term.

Move the negative one from the denominator of $\frac{P L}{- 1}$ .

$I = - 1 \cdot (P L) + \frac{- R}{- 1}$

Rewrite $- 1 \cdot (P L)$ as $- (P L)$ .

$I = - (P L) + \frac{- R}{- 1}$

Dividing two negative values results in a positive value.

$I = - P L + \frac{R}{1}$

Divide $R$ by $1$ .

$I = - P L + R$
