You can put this solution on YOUR website! The system below has how many solutions.
2x-y+4z=-5..............I
x+2y-z=6...............II
x+y+z=1..................III
EQN.II-EQN.III
Y-2Z=5......................IV
2*EQN.III-EQN.I
3Y-2Z=7........................V
EQN.V-EQN.IV
2Y=2
Y=1
1-2Z=5....OR.....2Z=1-5=-4
Z=-2
X+1-2=1
X=2
IT HAS UNIQUE SOLUTION WITH X=2,Y=1,Z=-2
IF THE EQNS.ARE DEPENDENT AND CONSISTENT YOU WILL GET INFINITE SOLUTION.
My answer is infinite, but I'm not sure. thanks so much for checking.
