Solve for r P=r+s-1

$P = r + s - 1$

Step 1

Rewrite the equation as $r + s - 1 = P$ .

$r + s - 1 = P$

Step 2

Move all terms not containing $r$ to the right side of the equation.

Subtract $s$ from both sides of the equation.

$r - 1 = P - s$

Add $1$ to both sides of the equation.

$r = P - s + 1$
