This math video tutors and gives instruction about solving systems of equations. The instruction is a brief and to the point teaching lesson on how to learn algebra and manipulate variables.
Systems of equations have two equations in two unknowns and the solution must be simultaneous for both. This technique is very powerful for solving complex story problems like mixture problems and the famous 'two trains leaving the station' problems.
