Rewrite as an equation.


To find the number, we need to put the words into an equation. Let's break this down.

"The sum of" always means that there are terms being added.

Whenever you see "of", it usually means multiplication.

The word "is" always means "is equal to" which can be represented by "#=#".

Let's put this together.

#1/5(x) + 3 = y#

Assuming there are two different "numbers", the final "number" would be some variable, for example: #y#.
