When you did this:
7 = 3r + 8s 7 = 2r + 5s - 2
3r + 8s = 2r + 5s -2
3r - 2r = 5s - 8s - 2
r= -3s - 2
You were ignoring the i and j parts. They are really still there. So you did this:
7i = 3ir + 8is 7j = 2jr + 5js - 2
and 7i =/= 7j
you cant take that step, you have to solve within the respective systems.
Nice job
