I am trying to build a website that runs on this equation. I know how to solve the equation for two variables that are in both equations but I have no idea how to solve for three variables where the two equations only have one in common. I am only in pre-algebra so if you can answer in a way that i can understand that would be great.

Here is the system of equations:

$10,000=mx+5000$

$y=1000x$

    $\begingroup$ there are three variables,$x,y,m$? $\endgroup$ Jan 3 '15 at 21:22
  • $\begingroup$ yes there are. any ideas? $\endgroup$ Jan 3 '15 at 21:24

Two equations for three unknowns should ring a bell... And indeed one cannot deduce $(x,y,m)$ from the two equations in your post. The most one can do is to write two of them as explicit functions of the third one.
