Which system of linear equations has an infinite number of solutions?
a. 3 x + 8 y = -1
3x + 8y = 2
b. 3 x + 8 y = -1
-3x + 4y = -20
c. 3 x + 8 y = -1
-12x - 32y = 4
d. 3 x + 8 y = -1
-2x + y = 3

Answer:

        c.      3x + 8y = -1

                 -12x - 32y = 4

Step-by-step explanation:

If we divide second equatoin by (-4) we get the first equation.

Two identical equations means infinite number of solutions.
