First you must solve this matrix manually and send the manual solution to me. (you must submit the manual matrix first) then you can start to develop your c++ program that can solve (any matrix) up to 15 equations with 15 unknowns. your program will be tested with a different matrix than the one given to you. your program should be able to read in the text file solve the the result on the screen as well as write the results to a text file. you dont have to do back substitution only solve for the value of one varible. there is information in teacher's hints on reading the two dimensional array into your program.
