Answer 1

Answer:

.......................................

Answer 2

Step-by-step explanation:

99x+101y=499

101x+99y=501

adding both equation ,we get

200x+200y=1000

dividing 200 on both sides

x+y=5. , let this equation name be A

99x+101y=499

101x+99y=501

subtracting both equation , we get

-2x+2y=2

-x+y=-1 let this equation name be B

adding A&B

x+y=5

-x+y=-1

we get

2y= 4

y= 2

and x=3
