AOA, I learned in this lecture how to use the matrix inversion method to solve a system of equations. I need to follow these steps to solve the equation: first, write the system of equations as a matrix equation; and second, find the inverse of A The inverse of A will be denoted by A-1, and then Multiply both sides of the equation by A-1 to isolate X. This will give you X = A-1B after that Solve for X by multiplying both sides by X-1, which is another way of writing A-1. This will give you X-1A = B. After these steps, check your solution by plugging in X into AX and verifying that it equals B.
