5x - 2y + 3z = -9
4x + 3y + 5z = 4
2x + 4y - 2z = 14
There are many different methods for solving this,
depending on what you are studying at the present
time. Please post again or email me telling
whether you are studying eliminating and substitution,
echelon method, Gaussian elimination, using
matrices, Cramer's rule using determinants, or the
inverse matrix method.
The solution in any case is (x,y,z) = (0,3,-1)
