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?

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.
