It's been a ten years ago when I learning those equations, some how recently my boss just give me a question and asking for help, I d't have any ideal back to carry out those equation where all the knowledge already give back to teacher, i guess.
Therefore, hope some one here can give me a little help on it. Thank you.
Writing those in linear equation,
a) x-y+z = 3
b) 4x-3y-z = 6
c) 3x +y+2z = 23
in the form of Ax=b. State the size of matrix A and its main diagonal elements
Thanks to Prove It Part 1 Solved
Using the elementary row operation (ERO) on the augmented matrix A|b, solve the system of linear equation above.
