does the equations form a linear system?

3z + x = -4
y + 5z = 1
6x + 2z = 3
-x-y-z = 4
please explain as well, thanks :)

Except the last one

anonymous · Answer

This does form a linear system because each of the terms are only to the first power.

anonymous · Answer

They all are, you're thinking of a linear equation, (which the last one is too actually).

anonymous · Answer

Oh, you are right
I misread it as equation of line instead of linear system

anonymous · Answer

what if you take that whole 4 equations together? will it form a linear system?

anonymous · Answer

You mean add them, then yes

anonymous · Answer

how about will you do that?

anonymous · Answer

since they all not all x y and z

anonymous · Answer

oh wait i think i know by just using two and a time to solve for each :P
