Declaring Variables

In this video we will be learning how to declare variables in word problems.

For example:

The length of a rectangle is 5 units longer than the width. If the perimeter is 22 units, how long is the width?

Let w = width

Let w + 5 = length

Perimeter Formula:  P=2l+2w

w + w + w + 5 + w + 5 = 22  w = 3
