Question

Jenna has 38 coins. She uses 19 coins to buy a notebook. How many coins does she have left?

Answer 1

Answer: 19 coins

Step-by-step explanation:

38-19=19

To check, take any one of the nubers and replace it with x, and when you solve for x. you'll get that number back. For example:

Let x represent the amount used to buy a notebook

19+x=38

x=38-19

x=19

Answer 2

38 coins - 19 coins = 19 coins

You solve the problem by subtracting how many coins she used by how many coins she has
