Question

2/x-3/y=15; 8/x+5/y= 77 .please solve the simultanious equeastion .plz try to solve this equations​

Answer 1

2/x-3/y = 15

8/X+5/y = 77

let 1/X be p and 1/y be q

2p-3q = 15. 1

8p+5q = 77. 2

EQ 2 - EQ 1*4

8p+5q = 77

8p-12q = 60

17q = 17

q = 1

X=1

EQ 1 --} 2p-3q = 15

2p = 18

p = 9

Y = 1/9

X = 1

Y = 1/9
