#### Solving Systems of Linear Equalities

When in the course of algebraic events, it becomes necessary for a student to finish their homework, and to solve a system of linear equations, a decent respect to the opinions of their math teache...

#### Systems of Linear Inequalities

Sorry, but life isn't always fair, and we have to deal with inequalities—even in math. Now we're going to cover how we deal with systems of linear inequalities. Yes, we know it's not fair. Are yo...

#### Graphing Linear Equations in Three Dimensions

The x and y variables of a system of linear equations match up with the x- and y-axes on a graph. There are two variables for two dimensions. When we add in a third variable, z, that means we trave...

#### Solving Systems with Three Variables

Three equations. Three unknown variables. If they aren't found in time, the whole world's supply of Silly Putty will go up in flames. Only one person can find them in time—and she just called in...
