Question 412185
<font face="Times New Roman" size="+2">


The second equation gives you half of your answer straight up without having to do anything.  Substitute that value for x into the first equation and then solve for y.  The x and y values then form an ordered pair (x,y) that represents your solution.


If you end up with a triviality, such as 0 = 0, then you have a consistent and dependent system, i.e. infinite solutions.  The graphical equivalent is that the two equations graph to the same line.


If you end up with an absurdity, such as 3 = 0, then you have an inconsistent system, i.e. no solution.  The graphical analogue is parallel lines.


If you end up with y = some specific number, then you have a consistent and independent system, i.e. one solution.  The graphical analogue is a pair of intersecting lines that intersect at the point represented by the solution set of the system.
