Give a description of the solution space to the linear system: x = 2 y = − 1. Give a description of the solution space to the linear system: − x + 2y − z = − 3 3y + z = − 1. 2z = 4. Nettet16. sep. 2024 · The system of linear equations AX = 0 has only the trivial solution, where A is the n × k matrix having these vectors as columns. The last sentence of this theorem is useful as it allows us to use the reduced row-echelon form of a matrix to determine if a set of vectors is linearly independent.
