Use the Given the equations below to answer the questions that follow:
5w + 4x + 3y + 2z = 30
2x + w + 3y + 4z = 30
6w + 3y - 2x – 2z = 3
4w + 3x + 4y – 4z = 6
(a) From the above system of simultaneous equations form a matrix (A) to represent the above
information.
(b) Find the determinant of the matrix A above
(c) Find the inverse of the matrix A above showing all your workings.
(d) Using the inverse method of matrix operations, solve the simultaneous equations above and
show the values of “w, x, y & z’
