Question 517413
<font face="Times New Roman" size="+2">


Let *[tex \Large x] represent the number of video games.  Let *[tex \Large y] represent the number of pinball games.  Since we want the number of each to be equal:


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ x\ =\ y]


Since video games cost 3 and pinball costs 2 and we have 30 total:


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ 3x\ +\ 2y\ =\ 30]


Substitute *[tex \Large x] in place of *[tex \Large y] (or vice versa if you like) and then solve the single variable equation.

*[tex \LARGE e^{i\pi} + 1 = 0]
My calculator said it, I believe it, that settles it
