Homework Help: Algebra - solving linear equations w/ substitution

Posted by Samantha on Monday, March 19, 2007 at 6:21pm.

The question in the book reads:
"Suppose you try to solve a system of linear equations using substitution and get this result. How many solutions does each system have?"
1)x=-2
2)y=12
3)6=x
4)-8=-8
5)7=y
6)5=3
I understand #3 and #6, but I do not understand how to know how many solutions there are to #1,2,3,or 5.
