Question 200857
{{{system(4x+4y+4z=-24, -2x+2y+3z=-29, 2x+14y+4z=-70)}}}

There are many different ways to solve this, and I have no
way of knowing which way you are studying.  So I'll just
post the answer, the ordered triple.  If you want to know how
to solve it, post again telling what method you are studying.
If I pick one way, it probably will be a different method.  So
let us know which way you are studying so we can help you
learn how to solve this using the method you are studying.

Answer:
(x,y,z) = (3,-4,-5)
