x=18/13
y=(-28)/26

Explanation:

3x+2y=2 --------------------(1)
2x-3y=6 --------------------(2)

3x+2y=2 --------------------(1) xx3
9x+6y=6 --------------------(3)

2x-3y=6 --------------------(2) xx2
4x-6y=12 -------------------(4)

9x+6y=6 --------------------(3)
4x-6y=12 -------------------(4) 3 +4
13x=18
x=18/13

Substitute x=18/13 in the equation (1)

3xx18/13+2y=2
54/13+2y=2
2y = 2-54/13=(26-54)/13=(-28)/13
y=(-28)/13 xx1/2=(-28)/26
y=(-28)/26
