Question 131701: For the following systems of linear equations:
a) Determine how many solutions exist
b) Use either elimination or substitution to find the solutions (if any)
c) Graph the two lines, labeling the x-intercepts, y-intercepts and points of intersection
2y + 3x = 7 and 8y + 12x = 28

You can put this solution on YOUR website!
8y+12x=28 now multiply the other equation by -4
-8y-12x=-28
-------------
0+0+0=0
0=0 these are the same equation and the same line when graphed.
No unique solution for x or y.
