Question 240738
<font face="Garamond" size="+2">


Just add the two equations term by term.  The coefficient on *[tex \LARGE y] in one equation is the additive inverse of the coefficient on *[tex \LARGE y] in the other equation.  When you add them, the *[tex \LARGE y] variable will be eliminated leaving you with a single equation in the single variable *[tex \LARGE x] that can be solved by ordinary means.  Once you have the value of *[tex \LARGE x], substitute it back into either of the original equations, and then solve for *[tex \LARGE y]


Check your answer by substituting both values back into both original equations to ensure that you have a true statement in each case.
