Oh yeah, doing it by hand’s alot easier…PSYCHE!

Sure, who wouldn’t love to solve a systems of equations in 10 minutes instead of 30 seconds, I would, wouldn’t you!? (lol… :D)

Without using matrices, there is probably not a way to find out specifically if the value of “z” has an infinite number of solutions (but I haven’t had AP calc yet either )


Yes, just type “and” with spaces before and after between equations and solve for the variable you want, or get it from the catalog.


:D
