Answer:

x=4, y=13. (4, 13).

Step-by-step explanation:

3x+2y=38

-6x+4y=28

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

simplify -6x+4y=28 into -3x+2y=14

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

3x+2y=38

-3x+2y=14

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

4y=52

y=52/4=13

3x+2(13)=38

3x+26=38

3x=38-26

3x=12

x=12/3=4

x=4, y=13.
