"What is the solution of the system of equations?"

How do you solve it when there are 3 of them? I'm probably over-looking something basic, aren't I?

are you supposed to solve with substitution or elimination...or does it matter ?

It doesn't matter, but I figured out a way to do it- I think.  I used the top equation to solve for z, then substituted the equation into the other two so that I had only 2 equations with 2 variables.  And then I could just solve it normally.  Then I went back and put what I got for x and y into the first equation to get z, and I was done.

I just kind of panicked because there were 3 equations, and I don't think I've ever worked with 3 before...
