Answer 2

Answer:

23x + 31y = 7 (equation 1)

31x + 23y = 47 (equation 2)

According to the question

let the equation 1

23x + 31y = 7

23x = 7-31y

x=(7-31y)/23 (equation 3)

Putting this value into equation 2

31x + 23y = 47

31×(7-31y)/23 + 23y = 47

(217 - 961y)/23 + 23y = 47

(217 - 961y + 529y)/23 = 47

217 -432y = 47 ×23

217 -431y = 1081

-431y=1081-217
