Solving Formulas

Solve for a variable. Start by selecting a formula and then click "Given".

Step	Operation	Perform	Result
Given			$\frac{9}{5} C + 32 = F$
	Subtract $32$ from both sides	$\frac{9}{5} C + 32 - 32 = F - 32$	$\frac{9}{5} C = F - 32$
	Multiply $\frac{5}{9}$ to both sides	$\frac{5}{9} (\frac{9}{5} C) = \frac{5}{9} (F - 32)$	$C = \frac{5}{9} (F - 32)$

Solution: $C = \frac{5}{9} (F - 32)$

Step	Operation	Perform	Result
Given			$P = 2 L + 2 W$
	Subtract $2 W$ from both sides	$P - 2 W = 2 L + 2 W - 2 W$	$P - 2 W = 2 L$
	Divide both sides by $2$	$\frac{P - 2 W}{2} = \frac{2 L}{2}$	$\frac{P - 2 W}{2} = L$

Solution: $L = \frac{P - 2 W}{2}$

Step	Operation	Perform	Result
Given			$V = l w h$
	Divide both sides by $l w$	$\frac{V}{l w} = \frac{l w h}{l w}$	$\frac{V}{l w} = h$

Solution: $h = \frac{V}{l w}$

Step	Operation	Perform	Result
Given			$A = \frac{x + y}{2}$
	Multiply both sides by $2$	$2 \cdot A = 2 (\frac{x + y}{2})$	$2 A = x + y$
	Subtract $x$ from both sides	$2 A - x = x + y - x$	$2 A - x = y$

Solution: $y = 2 A - x$
