SOLUTION: 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

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

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.
