I am entering precalculus but in order to finish the summer packet, I have to go all the way back to algebra. I need some refreshing on system of equations.
If you could explain how to do these problems and give me a summary of how to do the different methods, it would be extremely helpful.
These are the specific questions I am having trouble with, if you explain how to do them it would be a big help. Thanks.
1) 5x+4y=6 -2x-3y=-1
2) -2x+y=8 y=-3x-2
Any help would be appreciated, thanks in advance.
