Answer:

x=2, y=8. (2, 8).

Explanation:

y-2x=4

2x+3y=28

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

y=2x+4

2x+3(2x+4)=28

2x+6x+12=28

8x+12=28

8x=28-12

8x=16

x=16/8

x=2

y-2(2)=4

y-4=4

y=4+4

y=8

X is 2 and y is 8 because 8-2 sets of 2 which is 4 is equal to 4 and 2 sets of 2 which is also 4 plus 3 sets of 8 which is 24 is equal to 28.
