Ques.- Solve the following system of linear equation by matrix method (inverse method) .
12p + 4q + 17r +11s = 5
14p + 8q + 9r + 4s = 8
3p + 7q +2r + 5s = 12
5p + 12q +9r +7s = 7
12p + 4q + 17r +11s = 5
14p + 8q + 9r + 4s = 8
3p + 7q +2r + 5s = 12
5p + 12q +9r +7s = 7

Rather tedious to find the inverse of a 4by4 matrix, and out of the question to type it all out.
Surely you can find an inverse calculator on the web.
Just google and pick one
then multiply that inverse by
