For what value of a, would the system have an infinite number of solutions?
2x-y=5
8x-47=2a
A) 2 B) 4 C)5 D)10 E)20
when the lines are the same.
2x-y = 5
Hmmm. a typo - no y term in the 2nd equation.
Anyway, since there are 8x, the same line would be just 4 times the other.
8x - 4y = 20
Looks like a=10
