So here is the system:
V+W+X+Y+Z=7
X+2y+3z=8
x+2y+5z=10
I used Gaussian elimination method and got this:
V+W+X+Y+Z=7
X+2Y+3Z=8
-2Z=-2
So from here I can get z=1 but couldn't go up from here as the next equation (x+2y+3z)=8 has two other unknowns and the other is even worse with 5 variables. Anyone help please?
I was just wondering if there was a way I can find a solution to the variables even if it is something like 0=2 which means the system is unsolvable etc. So it is not possible to do anything beyond the point of getting the value of z as 1? So I just leave it that way and write 'system unsolvable?'
