Question 627084
<font face="Times New Roman" size="+2">


Multiply the first equation by 3, then add the two equations term-by-term.  Solve the resulting single-variable equation in *[tex \LARGE y] for *[tex \LARGE y].  Once you have a value for *[tex \LARGE y], substitute that value for *[tex \LARGE y] in either of the original equations and solve the resulting single-variable equation for *[tex \LARGE x].  If at any point the result is a triviality, such as *[tex \LARGE 0\ =\ 0], then you have a dependent system (infinite solutions).  If at any point the result is an absurdity, such as *[tex \LARGE 3\ =\ 0], then you have an inconsistent system (no solution).  Otherwise, you have a consistent and independent system with a solution set consisting of a single ordered pair formed from the calculated values of *[tex \LARGE x] and *[tex \LARGE y].

My calculator said it, I believe it, that settles it
