Question 174030: Ok, I just submitted this question so I am sorry for re-submitting it.
x+7y=8
x=6-7y
I plugged in x and I really don't know what I am doing wrong, I guess I should have added this in my first question about this problem:
6-7y+7y=8
6-14y=8
I think I am getting signs mixed up or something, but I have tried it different ways and cannot figure out what I am doing wrong.
