I'm confused about graphing or solving the linear equations for slope/intercept.

Question

Here is what I solved:
3x+2y=-6 X-4y=-16

2y= -3x-6 -4y=1x-16

Y=-3/2+3 Y=+1/4+4

My answer for graphing the systems for the lines to intersect...well, they didn't intersect. But the answer is (4,-1)

Can someone explain my problem? And help explain how to solve it?

I'm confused by your impatience and reposting the same problem...
