Question

Find A⁻¹ and use it to solve the equations. What equations are being referred to, and what is the solution process?

Answer 1

To solve equations using the inverse, you need to have a system of linear equations in the form of AX = B, where A is the coefficient matrix, X is the variable matrix, and B is the constant matrix. The solution process involves finding the inverse of A and multiplying it with B to get X, the solution.
