Show that if a nonzero matrix A is invertible and A multiplied by a matrix C equals 0, then C=0. Similarly, if C is invertible and AC=0, then A=0.
Added by Kyle B.
Step 1
We are given that A is invertible, which means there exists a matrix A^{-1} such that A^{-1}A = I, where I is the identity matrix. Show more…

Use part (c) of the Invertible Matrix Theorem to prove that if $A$ is an invertible matrix and $B$ and $C$ are matrices of the same size as $A$ such that $A B=A C$, then $B=C .$ IHint: Consider $A B-A C=0.1.$

The Invertible Matrix Theorem
Let $A=\left[\begin{array}{cc}{B} & {0} \\ {0} & {C}\end{array}\right],$ where $B$ and $C$ are square. Show that $A$ is invertible if and only if both $B$ and $C$ are invertible.
