Solving One-Step Equations with Subtraction

Solving one-step equations is easy with these simple steps.

We will use the same methods to solve subtraction equations as we did with equations that were addition problems. Except this time, can you guess what the opposite mathematical operation is going to be? You got it - Addition! We are going to add in order to get the variable by itself!

Here are a few examples!

Example 1

In example 2 we will see what happens when you have a negative number as your answer. Don't forget your integer rules!

Example 2

For extra help with this example, watch the following video. I will take you step-by-step through the entire process.

In our last example we will again deal with a negative numbers. We solve the problem the exact same way, but we have to make sure that we don't lose the negative. Take a look at this example.

Example 3

Are you starting to catch on? Yes! For subtraction equations, we must add in order to solve the equation. I bet you are now ready to solve multiplication equations.

What People Are Saying...

"I'd like to start off by relaying my sincerest gratitude for your dedication in teaching algebra. Your methodology is by far the simplest to follow, primarily because you take the time to include the small steps in between that most other teachers leave out.

It helps to know why you are doing something. I am 45 and heading to college to get my BS in Business. I need to brush up, hence the visit to your site. Great Job!"

Jimmy - United States

"I stumbled onto your site after I found out that I needed to use some fundamental algebra for an assignment. Turns out I had forgotten some things and your great site helped me remember them like "that" (snap of fingers). The organization of the site let me find exactly what I was looking for so easily. Kudos to you for maintaining such a great resource for students of all ages!"

Tom - United States

"I just wanted to write and basically thank you for making such a wonderful website! I'm 20 years old and about to take a basic placement test for college. I wanted to brush up on my Algebra skills and I stumbled upon your site. I'm amazed at how simple you make it and how fast I'm remembering Algebra! I don't remember getting most of the answers right when I had an actual teacher in front of me teaching this. Thanks a lot!"

Elizabeth - United States

"I am a pensioner living in South Africa. I stumbled on your website, the best thing that could ever happen to me! Your course in Algebra has helped me a lot to better understand the different concepts. Thank you very much for sharing your skills for teaching math to even people like me. Please do not stop, as I am sure that your teachings have helped thousands of people like me all over the world."

Noel - South Africa

This is an amazing program. In one weekend I used it to teach my Grade 9 daughter most of the introductory topics in Linear Relations. I took her up to Rate of Change and now she can do her homework by herself.
