Can someone help me with matrices on calculators? Ex. Problem is 4x-5y=33 and -x+5y=-27 http://www.algebralab.org/lessons/lesson.aspx?file=Algebra_matrix_systems.xml

OpenStudy (anonymous):

I don't know how to put the equations into matrix form to input on the calculator. The entire thing confuses me, actually.

OpenStudy (anonymous):

It explains it, but I still don't understand how they got there.

OpenStudy (anonymous):

Well, thank you for helping! I appreciate it.
