$x-13=3$

$16-13=3$
Therefore, $x$ is equal to $16$ .

See below.

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:

$color(red)(x-13=3)$

I hope that helps!
