Have you tried adding the two equations together? If so, what did you get?
OpenStudy (anonymous):

Looks very strange to me.
OpenStudy (radar):
Both equations are the same line: y = (3/2)x - 3 this is an identity. The 2nd equation is equal to the first equation. Multiply first equation by -1 and it becomes the 2nd equation. infinite number of solutions.
OpenStudy (anonymous):
If you add the equations you find 0x+0y=0 Every x y is a solution It s the equation of a line y=(3x-9)/2
