On your calculator, find the inverse. Step 2. Since matrix multiplication is no commutative, the order in which we multiply the matrices is very important. The inverse will always go first, so the equation will look like this: AX= B. A-1AX = A-1B We need to multiply by the inverse to both sides.

Inverse of a Matrix. Let A be a square matrix with dimensions n X n. The inverse of A (denoted ) is a square matrix such that . A matrix has an inverse if the matrix is square and is non-singular (the determinant ( 0). Example: Determine whether the following matrices have an inverse. If the matrix does not have an inverse, state why. a) b) c)

In class, we learned how to invert a matrix by constructing an augmented matrix and transforming the left-hand-side into the identity matrix using elementary row operations, at which point the right-hand-side is the inverse. Prove that this works in general. Solve the following system of linear equations using matrix inversion on your calculator:

Determine the inverse of the coefficient matrix. Multiply both sides of the matrix equation by the inverse matrix. In order to multiply the matrices on the right side of the equation, the inverse matrix must appear in front of the answer matrix.(the number of columns in the first matrix must equal the number of rows in the second matrix).
