$w=A/l$

Given:

$A = lw$

To isolate w divide both sides by $l$ giving

$A divide l = lw divide l$

$A/l = l/l w$

But $l/l=1 " and " 1 times w=w$

So we have

$A/l=w$

Normal practice would be to have what you are looking for (dependant variable) to be on the left

$w=A/l$

How do you solve for w in A = lwA = lw?
