Answer 2

Answer:

x=2, y=1

Step-by-step explanation:

27x+31y=85. (multiple by 27)

31x+27y=89. (multiple by 31)

729x+837y=2295. ....(i)

961x+837y=2759.......(ii)

now, sub eq (i)and (ii)

we get,

-232x=-464 ( - is cancel)

x=464/232

x=2. now put the value of x in 27x+31y=85

27×2+ 31y=85

54+31y=85

31y=85-54

y=31/31

y=1
