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

`(L)/(A) =LW` ⇒ Multiply both sides by A

`(LA)/(A)=LWA` ⇒ The terms 'A' on the LHS cancel each other

`L=LWA` ⇒ Divide both sides by 'L'

`(L)/(L)= (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
