Answer 2

Heya !!!

here is your answer !!!

9x + 2y = 8 --------(1)
2x + 9y = 5 -------(2)

on adding 1 and 2 equation we get !!

11 x + 11y = 13 ---------(3)

on subtracting 1 and second equation we get

7x - 7x = 3 --------------(4)

from equation 3 and 4 we get

x + y = 13 / 11

x - y = 3 / 7

=> 2x = 124 / 77

=> x = 62 /77

on putting the Value of x in equation 1 we get

=>9 ( 62 /77 ) + 2y = 8

=> 558 /77 +2y = 8

=> 2y = 8 - 558 /77

2Y = 616 -558 / 77

2Y = 58 / 77


y = 29 / 77




hope it helps you dear !!!

thanks !!!
