Solve for a P=a-b+c

$P = a - b + c$

Step 1

Rewrite the equation as $a - b + c = P$ .

$a - b + c = P$

Step 2

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

Add $b$ to both sides of the equation.

$a + c = P + b$

Subtract $c$ from both sides of the equation.

$a = P + b - c$
