Question

(a+b)x+(a+b)y=a^2-2ab-^2
(a+b)(x+y)=a^2+b^2
solve this question by cross multiplication method.
Give its full solution .
PLEASE GIVE ITS SOLUTON FAST ITS VERY URGENT

Answer 1

[ previous solution is in attachment ]


$\frac{y}{4 a{b}^{2} } = \frac{1}{ - 2 {b}^{2} - 2ab}$



$y = \frac{4a {b}^{2} }{ - 2 {b}^{2} - 2ab}$


$y = \frac{4ab \times b}{2b( - b - a)}$

By cancelling 4b of numerator by 2b of denominator we get 2

So,

$y = \frac{2ab}{( - b - a)}$


$y = - \frac{2ab}{(a + b)}$
