Question

solve 47x +31y =63 , 31x +47y = 15. ​

Answer 1

Answer:

47x+31y=63..........(i)

31x+47y=15........(ii)

(i)×31=1457x+961y=1953

(ii)×47=1457×+2209y=705

................................................

(-) -1248y=1248

y=1248/-1248=-1

putting y value in equation (i)

47x+31×(-1)=63

47x-31=63

47x=63+31=94

x=94/47=2

x=2

y=-1
