Question 162345
{{{system(2x+3y-z=0, x-2y-4z=14, 3x+y-8z=17)}}}
<pre><font size = 4 color = "indigo"><b>
There are lots of ways to solve this system.  But I
can't take the time to do it every possible way.  
What method are you studying?

Elimination, substitution, triangular method, 
Gaussian method using matrices with back substitution,
Complete Gaussian method using row-reduced-echelon
form, AX=B method using inverse matrix, Cramer's rule using
determinants?

I'll give you the answer, which is the same regardless
of the method you are studying:

{{{matrix(1,15, "(", "x", ",", "y", ",", "z", ")", "=", "(", "4", ",", "-3", ",", "-1", ")")}}} 

If you are having trouble with the particular method you are
studying, then post again, giving the method you are studying
and we can help you with that particular method.
