Question

99x+101y=499;101x+99y=501​

Answer 1

Answer:

x=3 , y=2

Explanation:

99x+101y=499_________ (1)

101x+99y=501__________(2)

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

200x+200y=1000

or x+y=5 ______________(3)

subtract equation (1) from (2), we get

2x-2y=2

or x-y=1_______________(4)

Add equation (3) and (4) , we get

2x=6 => x=3

Putting value of (X=3) in equation (3), we get

3+y=5 => y=2.
