Answer: x=2, y=-2

Explanation:

1) I will find x first, so make the amount of Ys same

3(5x+2y=6)

2(4x-3y=14)

2) 15x+6y=18

8x-6y=28

3) combine them together so Ys are all cancelled and 23x=46

4) x=2

5) for solving y, you can just plug in the x to any of that 2 equations, then 4(2)-3y=14

6) 8-3y=14

7) -3y=6

8) y=-2
