Question

71x+37y=253 37x+71y=287

Answer 1

71x + 37y = 253 → 2627x + 1369y = 9361
37x + 71y = 287 → 2627x + 5041y = 20377
                              --------------------------------- -
                                             -3672y = -11016
                                               y = -11016/-3672
                                               y = 3
71x + 37y = 253
71x + 37 . 3 = 253
71x = 253 - 111
x = 142/71
x = 2

x = 2 and y = 3
