Question 295767
Where are the following systems and the given system? 
I see one system.
2/3x - y = 2
multiply by 3
2x-3y=6
x + 1/2y = -3
multiply by 2
2x+y=-6

2x-3y=6
2x+y=-6

The third system is the same

    2x - 3y = 6 and 2x + y = 6
    6x - 3y = 6 and 2x + y = 10
    2x - 3y = 6 and 2x + y = -6
