Find out how to multiply two numbers using scientific notation. [1:59]
There are many different ways to solve a system of linear equations. In this tutorial, you'll see how to solve such a system by combining the equations together in a way so that one of the variables is eliminated. Then, see how to find the value of that variable and use it to find the value of the other variable. [5:03]
