Ответ:
The matrix can only have 5 pivot columns for the system to be linearly independent.
Remember that in the system of equations:
Ax = b
A is the coefficient matrix of the incognita vector x and b is the solution vector.
The extended matrix is
(A l b)
If the matrix has more than 5 pivot columns, then the system is linearly dependent.
