Question

Solve the equation for the letter L: A=LW

L = AW
L equals W over A
L = A − W
none of the above

Answer 1

$\frac{L}{A} =LW$ ⇒ Multiply both sides by A
$\frac{LA}{A}=LWA$ ⇒ The terms 'A' on the LHS cancel each other
$L=LWA$ ⇒ Divide both sides by 'L'
$\frac{L}{L}= \frac{LWA}{L}$ ⇒ The terms 'L' on the LHS cancel each other to '1' and the terms 'L' on the RHS will also cancel each other
$1= WA$

The correct answer is the last option = none of the above
