Answer:

the value of x = 3 and y = 3

Step-by-step explanation:

2x + y = 9 ------------ (1)

-2y -2x = -22 ------------ (2)

Subtract (1) from (2)

-2x -2y = -22

2x + y = 19

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

       -y = -3

        y = 3

Put the value of y in equation 1

2x + y = 9

2x + 3 = 9

2x = 9 - 3

2x = 6

x = 6/2

x = 3

Therefore, the value of x = 3 and y = 3
