Randomized for each page Refresh Find the values of x and y ?

11 x+ 8 y= 327................(A)

13 x+ 32 y= 1153................(B)

(A)× 4 → 4 × 11x +4 x 8y = 4x327

ie, 44x +32 y = 1308 .............(C)

(C)-(B) → 31x = 1308 - 1153

31x = 155

∴ x= 155/31

= 5

Put this value in (A) ,

11x5+8y = 327

ie, 55+8y = 327

∴ 8y = 327-55= 272

∴ y = 272/8

= 34

x= 5:: y= 34
