SUMMARY
The matrix equation [10, 1, 9; 1, 4, 3; 2, -1, 3] X = 3X can be solved by transforming it into the form (A - 3I)x = 0, where A is the given matrix and I is the identity matrix. This approach simplifies the problem to finding the eigenvalues and eigenvectors of the matrix A. The solution involves determining the characteristic polynomial and solving for the eigenvalues, which leads to the general solution X = kU, where k is a constant and U is the corresponding eigenvector.
