Question: In each case, solve the systems of equations by finding the inverse of the coefficient matrix. (a) 2x - 3y = 0 x - Ay

In each case, solve the systems of equations by finding the inverse of the coefficient matrix.
(a) 2x - 3y = 0
x - Ay = 1
(b) x + Ay + 2z = 1
2x + 3y + 3z = 1
4x + y + 4z = 0
