Thank you for helping me with the last problem Reiny and Bosnian.

However, I have one more problem that I need help with please and I have no idea how work the problem. I used an on line calculator to get the answer. It didn't give an explanation on how to do the problem though. I need to know how to do future problems like this one. Please help.

{Y=3x+1

Y=5x-3

Answer says x=-2 and y=7

Please explain steps. Thanks

Y=3x+1 ...(1)

Y=5x-3 ...(2)

By comparison of (1) and (2), we conclude that

3x+1=Y=5x-3

3x+1=5x-3

solve for x to get

2x=4

x=2

Put x=2 in (1) to get

Y=3(2)+1=7

Check:

put x=2 in (2) to get

Y=5*2-3=7

If your program gives x=-2 and y=7, there must be a typo somewhere. Check your post.
