Web17 de set. de 2024 · Consider the system of linear equations A→x = →b. If A is invertible, then A→x = →b has exactly one solution, namely A − 1→b. If A is not invertible, then … WebAnswer: We only allow square matrices to have inverses because it's useful for inverses to be two-sided: that is, it's useful to have AA^{-1} = A^{-1}A = I, where A is the matrix, A^{-1} is its inverse, and I is the NxN identity matrix. For example, doing this makes it so that matrices are unique...
