Answer: Substitute the second equation into the first equation to eliminate y and solve for x:
2x + 3y = 6
2x + 3(-2/3x) = 6 // Substitute y=-2/3x
2x - 2x = 6
0 = 6
This equation is not true, which means that there is no solution to the system. Geometrically, this means that the two lines represented by the equations are parallel and do not intersect, so there is no point that satisfies both equations simultaneously.
