-2x1 +3x2 + mx3 =5
2x1 –3x2 - 4x3 = -7
-X1 + 2x2+2x3 = 2

Rewrite the system in the format Ax = b and determine the following:

a. Find the value for m such that det(A) = |A| = 1 using cofactor expansion along the first row (R1).
b. Based on the given value of the determinant, identify the type of system (consistent/inconsistent) and the corresponding number of solutions.
c. Based on the given value of the determinant, how many row/column vectors of A are independent and what is their span?
D. Using your m value from part A, determine the following:

a. Find the following cofactors: C21, C22, C23
b. Find the inverse of A using MATLAB. Write down everything you typed into MATLAB to find the inverse, including your A matrix. Identify on your paper where your cofactors are located in the inverse.
c. Solve the system of equations using the inverse of A.
