Question

Determine which system below will produce infinitely many solutions. (2 points)

1) -4x + 6y = 20   
    4x - 3y = -2

2) -2x + 4y = 18   
     4x - 8y = -36

3) 3x - 2y = 5         
   -6x - 4y = -10

4) 5x - 3y = 12       
    15x - 9y = 24

Answer 1

The only system that has infinitely many solutions is NUMBER 2. Where you solve a system, and both sides end up being 0=0, then the system will have infinitely many solutions. Well, in these four choices, Number 2 is the only one that ends up being 0=0 after I solved it.
