Please give step by step instructions and name each step like triangular form, augmented matrix etc so I know when and what to do and can understand it. We are not using calculator so the steps need to be shown to the solution. 1) Compute u + v and u - 2v u = -1 ; v = -3 2 -1 2) Display the following vector

I am having problems coming up with the equations(systems)to use for the following word problem. I don't usually have a problem with solving matrices infact I like them but I can't even get started on this problem. A company produces two products, A and B For each unit of A sold the profit is $8, and for each unit of B the pr

I am to use matrix reduction on this problem. I can solve systems by matrixs with out any problem but I can't seem to set up the two equations for this problem so that I can even turn them into a matrix and solve.
