Answer 2

Answer:

x=5

y=2

Step-by-step explanation:

x+2y=9------[1]

2x-y=8-------[2]

multiplying [2] by 2 we get,

4x-2y=16------[3]

adding [1] and [3] we get,

     x+2y=9

[+] 4x-2y=16

----------------------

    5x=25

x=5

substituting the value of x in [2] we get

2x-y=8

10-y=8

-y=8-10

-y=-2

y=2
