Question

A.) Write the linear system as a matrix equation in the form AX=BB.) solve the system using the inverse that is given for the coefficient matrix

Answer 1

Explanation:

For the part A of the given question

we are to write the system of equations in the form AX= B

$\begin{gathered} x-y+z=0 \\ 2y-z=1 \\ -7x-8y=-5 \end{gathered}$

We need to extract the coefficients of x, y and z accordingly

To do so, we will have
