Answer:

The number is 13.

Explanation:

"A number" is a number we don't know to begin with. It should be represented by a variable. Let's use n. We'll probably be trying to find this number.

"increased by" usually means that there is adding going on here.

So far, we have:

n + 7

that is algebra for "A number increased by 7"

"gives 20" is a little strange wording, but it means yields or equals.

So now we have the whole equation:

n + 7 = 20

To solve, subtract 7 from both sides (of the equal sign)

n = 20 - 7

n = 13

The number is 13.

Check:

13 increased by 7 gives 20?

13 + 7 = 20 ?

20 = 20 ✔Yes! Done!
