duds: What is the easiest way to solve a matrix problem in algebra?
I am currently enrolled in intermediate algebra class. I found it to be interesting until we discussed matrices! I do not know how to solve it. I understand the goal of having the main diagonal line to be 1 and three zeros. However, I find it hard. Is there an easy way to solve a matrix?

That is the easy way. Wait until you had to solve 5 unknowns with 5 equations. Try to do without using matrix, and you will how annoying that is. For example, if you 2 equations, and you need to solve for 2 unknowns, then it’s not worth it to use matrix, since substitution or cancellation of variables will get the job done.
Not everything in life can be done by shortcuts, and that statement is true for mathematics too.
