1. ## Solving Systems Help.

per my other posts..Im trying to tutor my son. Im basically going to put the problems and answers I come up with..I just want someone to double check them if that is ok.
Solve using substitution:
2x = 1 - y
5x - 10y = -10

I come up with the answer:

y=1 x=0

2. ## Re: Solving Systems Help.

I keep getting this answer { x = 19/8, y = 53/8 } for problem:
Solve using substitution:
7x - y - 2 = 8
3y - 5x = 8
HOWEVER I need to break it down and DO NOT KNOW HOW TO BREAK IT DOWN!

I would convert [1] to $\displaystyle y=7x-10$.
Then substitute into [2], $\displaystyle 3(7x-10)-5x=8$
