Question 232409
In order to do this, you need a SYSTEM of equations--that means TWO equations with two variables.  


I have an explanation of this topic that might be easier to understand than your traditional textbook. To see it visit my own website.  Do a "Bing" or "Google" search for my last name "Rapalje".  Look for "Rapalje Homepage" near the top of the search list.  From my Homepage, look for "Basic, Intermediate, and College Algebra: One Step at a Time."  Select "Basic Algebra" and look in "Chapter 4" for "Section 4.07 Systems of Equations."  This section is supported by my "MATH IN LIVING COLOR" page in which I solved problems IN COLOR!
