Solve the equation for the letter l: a=lw

l = aw
l equals w over a
l = a − w
none of the above

 ⇒ Multiply both sides by A
 ⇒ The terms 'A' on the LHS cancel each other
 ⇒ Divide both sides by 'L'
 ⇒ The terms 'L' on the LHS cancel each other to '1' and the terms 'L' on the RHS will also cancel each other


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