- In Exercises 20-23, solve the given matrix equation for X. Simplify your answers as much as possible. (In the words of Albert Einstein, Everything should be made as simple as possible, but not simpler.) Assume that all matrices are invertible. ABXA1B1=I+Aarrow_forwardIn Exercises 48-63, use the Gauss-Jordan method to find the inverse of the given matrix (if it exists). 63. over ℤ7arrow_forwardIn Exercises 5-8, write B as a linear combination of the other matrices, if possible. B=[223002002],A1=[100010001], A2=[011001000],A3=[101010001], A4=[111011001]arrow_forward
