Question 986516: find 3 unknown values in the multiple equations
x+2y−3z=−2
x−y+z=−1
3x+4y−4z=4
2. 2x+6y+3z=2
x+3y+z=1
x+5y+2z=-4
find 4 unknown values
3. x+2y-3z+4w=12
2x+2y-2z+3w=10
0+y+z-2w=-4

You can put this solution on YOUR website!
1.  x=0, y=5, z=3
2.  x=17/2, y=-5/2, z=0
3.  x=5/3-1/2k, y=1/2k-1/3, z=3/2k-11/3, w=k  (has infinitely many solutions)
