Nancy sold 18 fewer boxes than lucas. how many boxes did lucas sell?

This question is incomplete. Here is the complete question:

Nancy have sold 19 box in total. Nancy sold 18 fewer boxes than Lucas,

How many boxes did Lucas sell?

The correct answer is 37.

Step-by-step explanation:

First we must analyze the data we have.

We know that the total number of boxes sold by Nancy is 19.

We know that Nancy sold 18 boxes less than Lucas.

But we don't know how many boxes Lucas sold, so we'll assign an x.

Now, knowing that Nancy sold 18 boxes less than Lucas, and that 19 is the total, the equation will be as follows:

x-18 = 19

The next thing we should do is try to make the term x remain alone, therefore we must move the -18, always remembering that a sum or a subtraction passes to the other side with the opposite sign. Then it will be:

x = 19 + 18

Then we solve the operation:

x = 37

In this way the variable x already has a result that is 37.

Therefore the correct answer is that Lucas sold 37 boxes.
