Question

$(99x + 101y = 499)(101x + 99y = 501)$
​

Answer 1

Answer:

$x = 3$

$y = 2$

step-by-step explanation:

$99x + 101y = 499 = = = = = = = > (1)$

$101x + 99y = 501 = = = = = > (2)$

On Adding (1) & (2), we get:

$200x + 200y = 1000 = = = = = = > (3)$

On subtracting (1) & (2), we get:

$2x - 2y = 2 = = = = = = > (4)$

On simplifying equations (3) & (4), we get:

$x + y = 5 = = = = = = > (5)$

$x - y = 1 = = = = = > (6)$

Solving equations (5) & (6) , we get:

$x = 3$

$y = 2$
