Here's the answer...Hope it helps u...

Answer 2

hey mate

here is your answer

Let us use a trick to solve it quickly

99x + 101y = 499 ............ i

101x + 99y = 501............ ii

subtract i from ii

2x - 2y = 2 or x - y =1 or x = 1 + y ....... .............................................. iii

add i and ii

200x + 200y = 1000 or x + y = 5 ...................................................................... iv

Now from iii and iv , we get 1 + y + y = 5 or 2y = 4 or y = 2 ...... v

again from iii and v , we get x = 1 + 2 = 3

Hence x = 3 , y = 2
