Question

How do you write an equation representing thirteen less than a number x is three?

Answer 1

`x-13=3`

Explanation:

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

Answer 2

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:

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