Solve for x and y37x+43y=123 43x+ 37y=117

Answer» 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
