Steps:
1. Multiply the first line by 3 and the second by 2
3 (3x + 2y = 4)
2 (8x - 3y=-6)
2. New lines are
9x + 6y = 12
16x + - 6y=-12
3. Now add/subtract them
25x + 0 = 0
25x=0
4. Divide by 25
X=0
5. To find y, substitute the 0 in the x in one of the equations
9x + 6y = 12
9 (0) + 6y = 12
6y = 12
6. Divide by 6, your Y=2
7. X=0, Y=2
