Given are two equations in two unknowns:

(a) Define a column vector X =  of unknowns, and find the matrix A and the vector Y, such that the given equations can be written as AX = Y. Manually, by repeated substitution find a and z. Then, in the Command Window find A-1 and X = A-1Y.

(b) Now, redefine X, A, and Y such that the given equations can be written as XA = Y, and manually find A-1 and X. Does the solution agree with the solution of part (a)? How is the matrix A of part (a) related to the matrix A of part (b)?

First of all, the writer made sure that he completely understood my assignment and all the guidelines before he began writing. My paper was finished very fast and well before the specified deadline. I thought it was written excellently. He definitely completely grasped the topic. Overall, he is a great writer and I couldn't have asked for better.
