Hi

Using your method of choice, what is the ordered pair?

  x=7y+1

-3x+2y=-3 

*Below is how far I've gotten before I got stuck:

-3(7y+1)+2y=-3    |You have chosen substitution.  Great choice!

-21y-3+2y=-3

-19y-3=-3

 -19y = 0         |Good work thus far

    y = 0  and x = 1   Ordered pair(1,0) the solution for this system
