What is matrix inverse method?

In the MATRIX INVERSE METHOD (unlike Gauss/Jordan), we solve for the matrix variable X by left-multiplying both sides of the above matrix equation (AX=B) by A–1. Typically, A–1 is calculated as a separate exercize ; otherwise, we must pause here to calculate A–1. The left side (above) is easy to calculate.
