Question 1155341
.


Dear tutor @mananth,


it looks like you need a special helper, who will check after you.

Not every student in high school is able to solve 4x4 matrix equation manually.


Even with simplifying which goes from +1 and -1 in arguments, it is difficult treat for an average student.


Therefore, I think that the meaning of this problem is to get the system of equations for 4 unknown coefficients,

and then solve it (almost mechanically) using a pocket calculator and its matrix functions / solvers.
