Question

If x/y=4, x-y=9, and y-x=(-9) then what is x and y?

Answer 1

from the first equation, x/y=4, we can find that x=4*y.
If we fill this in into the second equation, we get that:

x-y=9
<=> (4*y)-y = 9
<=> 3*y=9
<=> y=3

Knowing that y=3, we fill this in into our first equation and we get that:

x=4*y, so that x=4*3=12

So, y=3 and x=12

Answer 2

Thank u sooo much!! I couldn't have gotten it by myself. =D

Answer 3

Name the ordered pair if the x-intercept is -2.
