5) Multiply first equation by 5.
5x  20y = 60
6) Multiply first equation by 4.
4y  24x = 12
Subtracting first equation from the second, what does that tell you?posted by PsyDAG

what is the answer for 5 and 6
A.one
B.two
C.infinitely many
D. noneposted by Victoria

I need help can someone help me.

come on. For #5, you have
5x20y=60
5x20y=60
They are the same equation. So, any solution to one is also a solution to the other.
Try a similar comparison for #6 and just think about what it means.posted by Steve

thank you so much. thanks
