  Problem 2 – Inverse Method Now let’s use a quick method for using matrices to solve systems. Recall that matrix A contains the coefficients of x and y and matrix B contains the constants. To do this, multiply the inverse of matrix A by matrix B. Enter the command [A]-1([B] and press (. The resulting matrix contains the solution.
