Match each system of equations with its number of solutions

1st: 0 solutions

2nd: infinitely many solutions

3rd: 1 solution

Step-by-step explanation:

1st: add both equations and the result is 0 = 4 ⇒ inconsistent, no solution

2nd: add both equations and the result is 0 = 0 ⇒ it's true, for all x and y values

3rd: add both equations and obtain: 16x = 32 ⇒ x = 2,

then if you want to obtain y, replace x in any of both equations.

Conclusion is that only 1 solution (x = 2 and a unnique value for y) is obtained.
