Question

solve the following equation.​

Answer 1

Answer:

solution=(x,y)=(3,2)

Answer 2

Answer:

x=3

y=2

Step-by-step explanation:

Hii mate ^_^

101x+99y=501 .....(1)

99x+101y=499 .....(2)

Adding (1) and (2) , we get

200x+200y=1000

=>200(x+y)=200(5)

=>x+y=5   ......(3)

Subtracting (2) from (1), we get

2x-2y=2

=>2(x-y)=2(1)

=>x-y=1   .......(4)

Adding (3) and (4) , we get ,

2x = 6

=> x = 6/2

=> x = 3

Putting value of x in (3) , we get

3+y=5

=>y=5-3

=>y=2
