We can describe mathematically how the parts of a linear system relate to one another and to the input using a system of linear equations. If a linear system has n parts (where n is some number), then ...

It shows you how to solve for x+y when x + xy + y =54 and x and y are positive integers. The video solves it via factoring. I solved it in Python. Here are two ways to do it. The first is the ...

Gaussian Elimination. The general procedure learned to solve a system of linear equations is Gaussian elimination. The goal is to apply row operations to "eliminate" all the variables except for one ...

Physics and Python stuff. Most of the videos here are either adapted from class lectures or solving physics problems. I ...

Find out how to solve simultaneous equations using a graph in this Bitesize KS3 maths video. ... Simultaneous equations are often two linear equations that can be plotted on a set of axes.
