Question

Tamara purchased 31 cases of tile to use on her bathroom floors. She use it she used 17 in her upstairs bathroom and the rest downstairs bathroom. Write an equation to express how many cases used in her down stair bathroom ​

Answer 1

The correct equation would be 17 + x = 31

All you need to do is do 31 - 17 = 14 and x = 14 will be your answer!

Answer 2

In this question, we're trying to make a equation for the given information in the question.

We know that Tamara bought 31 total cases of tiles

We also know that she used 17 of those cases in the upstairs bathroom, while using the rest in the downstairs bathroom.

Since we know she started with a total of 31, our equation would equal to 31

We could represent the downstairs bathroom as "x"

Right now, our equation looks like this:

31 = x

However, since she used 17 of those tiles already, we would need to add 17 to our equation

31 = x + 17

The reason why we add 17 is because when we solve for the equation, we're going to have to subtract 17 from 31, and that would represent the amount of tiles she has left.

If you solve the equation

31 = x + 17

14 = x

She would have 14 tile cases left for the downstairs bathroom

Answer:

31 = x + 17
