Identify which equations have one solution, infinitely many solutions, or no solution.

Let's label them 1-6, for convenience.

1. 1 solution (a positive # of ys equaling a positive constant)

2. Infinitely many solutions (You get 0=0 if you completely simplify)

3. No solution (take out the 3z's; 2.5 doesn't equal 3.2)

4. Infinitely many solutions (take out the 3/4 x; 1.1+2 = 3.1)

5. No solution (take out the 4.5r; 0 doesn't equal 3.2)

6. 1 solution (x = 3 1/2)

if x = 1, then the answer is 3.5

4y - 6 + y^2 - 9 = y^2 + 4y - 15
