First expand the system and then use simultaneous equations to get x=5 and y=4

Explanation:

Expanding and simplifying the system

2(x-4) + y =2x-8+y=6

Therefore,
2x+y=14 (1)

3x -2(y-3) =3x-2y+6=13

Therefore,
3x-2y=7 (2)

Simultaneous Equations

(2 times (1)) + (2)

4x+2y+28 (1)
3x -2y=7 (2)

Cancel out the y terms and equate:

7x=35
x=5

Sub x back into (1):

2(5)+y=14
y=4
