See below.

#### Explanation:

We are given "thirteen less than a number x is three," and we are asked to form an equation to model this relationship.

Let's start translating from English to Math. "Thirteen" is $13$ and "three" is $3$. Now, we have "$13$ less than a number $x$ is $3$."

In math, "is" usually means "equals to." So now we have something more like an equation: "$13$ less than a number $x$ $=$ $3$.#

We are left with "less than a number." We can rewrite this as:

$\textcolor{red}{x - 13 = 3}$
