Solve for s P=b+2s

$P = b + 2 s$

Step 1

Rewrite the equation as $b + 2 s = P$ .

$b + 2 s = P$

Step 2

Subtract $b$ from both sides of the equation.

$2 s = P - b$

Step 3

Divide each term in $2 s = P - b$ by $2$ and simplify.

Divide each term in $2 s = P - b$ by $2$ .

$\frac{2 s}{2} = \frac{P}{2} + \frac{- b}{2}$

Simplify the left side.

Cancel the common factor of $2$ .

Cancel the common factor.

$\frac{2 s}{2} = \frac{P}{2} + \frac{- b}{2}$

Divide $s$ by $1$ .

$s = \frac{P}{2} + \frac{- b}{2}$

Simplify the right side.

Move the negative in front of the fraction.

$s = \frac{P}{2} - \frac{b}{2}$
