Question

 127x+59y=1928.......(1)
59x+127y=1792.........(2)​

Answer 1

Answer:

x = 11 & y = 9

Step-by-step explanation:

Add (1) & (2)

127x+59y+59x+127y = 1928+1792

127(x+y) +59(x+y) = 3720

(x+y) (127+59) =3720

(x+y) (186) =3720

x+y = 20 -----(3)

Subtract (2) from (1)

127x+59y-59x-127y = 1928 - 1792

127 (x-y) - 59(x-y) = 136

(x-y) (127-59) = 136

(x-y) (68) =136

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

Eq (3) * 1 x+y =20

Eq (4) * 1. x-y =2

2x=22

x= 11

Putting in (1)

11 + y =20

y = 9

Hope it helps you!!!!!!
