Question

99x + 101y= 499

101 x +99y = 501​

Answer 1

Step-by-step explanation:

99x + 101y =499 ....(1)

101x + 99y = 501 ....(2)

adding equation (1) and (2), we get

200x + 200y =1000

or x+y = 5 ...(3)

subtracting (1) from (2) we get ,

2x - 2y = 2

or x-y = 1 ....(4)

adding (3) and (4) we get

2x=6

x=3

putting value of x in (3) we get

y = 2
