Algebra - solving linear equations w/ substitution

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?"
I understand #3 and #6, but I do not understand how to know how many solutions there are to #1,2,3,or 5.
