Solve using the elimination method. If a system is inconsistent or dependent, so state. For systems with linear dependence, write solutions in set notation and as an ordered triple in terms of a parameter. $$\left\{\begin{array}{l} 4 x-y+2 z=9 \\ 3 x+y+5 z=5 \end{array}\right.$$

Solve using the elimination method. If a system is inconsistent or dependent, so state. For systems with linear dependence, write solutions in set notation and as an ordered triple in terms of a parameter. $$\left\{\begin{array}{l} 2 x-4 y+5 z=-2 \\ 3 x-2 y+3 z=7 \end{array}\right.$$
