Question
For what value of x is determinant of M=0?
7 Solve the following simultaneous equations by
matrix inverse method and crammer's rule
(a) x, 2x, + Xy = 6
X + 4x, + 2x, = 7
%3D
2x2 - X3 = 0
(b) x + 2y = 13
2x + 3 y = 21.
(c) 2x + 3 y - z + 3 = 0
x - 4y + 2z - 14 = 0
4x + 2y - 3z + 6 = 0
8. Solve the equation
