  1. 37x + 43y = 123 ……..(1)43x + 37y = 117 ……..(2)Adding (1) and (2)80x + 80y = 24080(x + y) = 240x + y = 240/80 = 3 ……..(3)Subtracting (1) from (2),6x – 6y = -66(x – y) = -6x – y = −6/6 = -1 ……..(4)Adding (3) and (4)2x = 3 – 1 = 2⇒ x = 1Subtracting (4) from (3)2y = 3 + 1 = 4⇒ y = 2Hence, solution is x = 1, y = 2
    Try with elimination method
    Ans 1 and 2
    This will be done by addition and subtraction
    1&2
