The given system of eqns. has infinitely many solutions.

Name the given eqns. $2x-3y-z=0..............................<<1>>.$

$3x+2y+2z=2...........................................................<<2>>.$

$x+5y+3z=2..............................................................<<3>>.$

Observe that, adding $<<1>> and <<3>>," we get "<<2>>.$

Therefore, the given system of eqns. has infinitely many solns.
