Problem 3. True-False Questions. Justify your answers. (a) If a homogeneous linear system has more unknowns than equations, then it has a nontrivial solution. (b) The reduced row echelon form of a singular matrix has a row of zeros. (c) If A is a square matrix, and if the linear system Ax = b has a unique = c also must have a unique solution, then the linear system Ax solution. (d) An expression of an invertible matrix A as a product of elementary matrices is unique.
