Question

How do you write the algebraic formula for: When you add 18 to 1/4 of a number you get the number itself?

Answer 1

See a solution process below:

Explanation:

First, let's call "a number": `n`

Then we can write "1/4 of a number" as:

`1/4 xx n` or `n/4`

We can next add the phrase "When you add 18 to" as:

`n/4 + 18`

The phrase "you get the number itself" means the previous part of the sentence is "equal to the number itself" and we can now write:

`n/4 + 18 = n`
