Homework Help: Math

Posted by Momo on Saturday, February 6, 2010 at 6:46pm.

Graph the solution:

3x-y-7<0
x+5y+3>=0

This is my thought process in this:

The first equation I can solve for y since we don't have to worry what x is. And I get y>3x-7.

The second one, however, y is being multiplied by 5, so I can't just divide by 5 on both sides because I don't know if the value of y will be positive or negative (and then I'll have to switch the sign).

...So I don't know about the second equation. Help please?

Thank you!
