Question:
Determining K for Linear System with Infinite Solutions
1. Determine all values of k for which the given system has an infinite number of solutions:
x1 + 2x1 + x3 = kx1
2x1 + x2 + x3 = kx2
x1 + x2 + 2x3 = kx3
Figure that the determinant for the matrix in the system is -4. I just don't know how to use that to determine the solution of this problem.
