Question

if 9x - 11y = 4x + 13y find value x² + y² / x² - y²
​

Answer 1

$\huge\sf\bold{Solution}:-$

$9x - 11y = 4x + 13y$

$9x - 4x = 13y + 11y$

$5x = 24y$

$\frac{x}{y} =\frac{24}{5}$

$Now ,$

$\frac{(x² + y²)}{(x² - y²)}$

$\frac{(24)²+(5)²}{(24)²-(5)²}$

$\frac{576+25}{576-25}$

$\frac{601}{551}$
