Question 1008109
There are 3 unknowns but only 2 equations
It can't be solved directly
(1) {{{ x*y*z = 54 }}}
(2) {{{ x + y + z = 14 }}}
-------------------
I stared at it for a while, and I got:
{{{ x = 2 }}}
{{{ y = 3 }}}
{{{ z = 9 }}}
-------------
(1) {{{ x*y*z = 54 }}}
(1) {{{ 2*3*9 = 54 }}}
and
(2) {{{ x + y + z = 14 }}}
(2) {{{ 2 + 3 + 9 = 14 }}}
--------------------
Other than trying numbers to see
what works, I don't know any other
way to solve it. You might want 
a 2nd opinion.
