To show more detail from what Kate is saying, I will "solve" this system using elimination method
2x - 3y = 6
-2x + 3y = -6
0x + 0y = 0
0 = 0
Since neither variable remains, we cannot solve for a variable. Since the statement is true (0 does equal 0), we know that the equations are two forms of the same line
There is an infinite number of solutions.

Is this a system of equations you are supposed to solve? Because the solution to that would be "any x and y where y = -2 + (2/3)x". These two equations are essentially the same thing, as you can get one from the other by multiplying both sides by (-1).
