Question

ay/b-by/a=a^2-b^2. find value of y

Answer 1

we can actually undsitribute the y

$y( \frac{a}{b}- \frac{b}{a})=a^2-b^2$
divide both sides by $( \frac{a}{b}- \frac{b}{a})$
$y= \frac{a^2-b^2}{ \frac{a}{b}- \frac{b}{a} }$
times the right side by (ab/ab)
$y= \frac{ab(a^2-b^2)}{ a^2- b^2 }$
y=ab
