Question

5x-13y=3x-8y, what is the value of x2+y2/x2-y2​

Answer 1

${\huge{\boxed{\tt{\color {red}{Answer❀✿°᭄}}}}}$

➪ 5x - 13y = 3x - 8y

➪ 2x = 5y

➪ Let, 2x = 5y = 10a

➪ So, x = 5a, y = 2a.

➪ Therefore, (x*x + y*y) /

(x*x - y*y) = {(x^2) + (y^2)} /

{(x^2) - (y^2)}

➪ 29(a^2) / 21(a^2)

➪ (29 / 21).
