Sorry I posed one before this and didn't finish the problem.
42. How many solutions does the system have?
3x + 12y = 20
y = –1/4x + 5/3
I'm not sure what the answer is, I am bad at these.

The lines have different slopes, so they are not the same line, and not parallel. They have to intersect somewhere.
