Question

Arrange the following in correct order to solve a linear system \(AX=T\) using matrix inversion. A. Verify that determinant of \(A\) is non-zero B. Compute the adjoint C. Compute \(A^{-1}\) D. Multiply \(A^{-1}T\) to get \(X\) E. Set up the co-efficient Matrix \(A\) and constant Matrix \(T\).

• A. E, A, B, C, D
• B. A, B, C, D, E
• C. E, B, A, D, C
• D. E, A, B, D, C

Hint:

To solve \(AX=T\) by matrix inversion, first form \(A\) and \(T\), check \(|A|\neq0\), find adjoint, find inverse, then calculate \(X=A^{-1}T\).

Answer 1

The Correct Option is A
