37 x + 43  y = 123      ----(1)

       43 x + 37 y = 177      --- (2)

(1) - (2)  :        - 6 x + 6 y = - 54

        =>           x - y = 9         --- (3)

(1) + (2) :    80 x + 80 y = 300

       =>          x + y = 15/4             -- (4)

       add (3) and (4):        2 x = 9 + 15/4 = 51/4

        =>                           x =  51/8

        =>                           y = x - 9 = -21/8
