Question 28602: Here's another one. I am not sure but I think that there may be no solutiuon to this.
x -y + z = -3
x + y + z = 3
x + y -z = 7
Answer by longjonsilver(2297)   (Show Source):
You can put this solution on YOUR website! let matrix = A
detA = 1(-1-1)--1(-1-1)+1(1-1)
detA = -4
Now, sub the -3 3 7 column for the x-values, and recalc the det of that --> -8
so x = -8/-4 --> 2
Now, sub the -3 3 7 column for the y-values, and recalc the det of that --> -12
so y = -12/-4 --> 3
Now, sub the -3 3 7 column for the z-values, and recalc the det of that --> 8
so z = 8/-4 --> -2
--> this is Cramer's Rule.
