Please show all steps clearly. Also please use m=0, f= 7 and l=5 in the equation above and the solve accordingly.

After ensuring that the determinant of the coefficient matrix is not zero, write down the matrix equation Ax = b for the set of linear equations, clearly indicating the matrices involved. Perform row operations on the augmented matrix [A]I] to find the inverse of matrix A. Use class/video conventions to indicate row operations. If you use any other conventions you will receive 0 points even if your answer is correct. Perform matrix multiplication A-b to get values of variables x, y, and z.
