Question 448022
<font face="Times New Roman" size="+2">


Notice that the coefficients on the *[tex \Large y] variables are already additive inverses (1 and -1), so the system is already set up to solve by the elimination method.


Add the two equations:


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ x\ +\ x\ +\ y\ -\ y\ =\ 5\ -\ 9]


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ 2x\ =\ -4]


You should be able to take it from here.

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