Now that you know all the rules for solving one-step equations, solving two-step algebra equations will be a piece of cake! You will need prior knowledge of solving one-step equations in order to understand this lesson.
There are 5 examples to this lesson, so make sure that you keep scrolling down to learn how to solve all types of two step equations.
Each equation is going to be solved in two separate steps. Let's take a look:
Notice that in order to get x on the left hand side by itself, (x = ) we need to remove the 3 and the 2. Therefore, this equation will involve two separate steps.
Remember that you must use the opposite mathematical operation in order to remove a number from one side of an equation.
There's one rule to remember when solving two-step equations:
Let's solve this example together. Notice how two separate steps are involved in solving this equation!
We'll look at another example similar to this one.
For more clarification on example 2, take a look at the following video...
The Algebra Class E-course goes through each step of solving two-step equations within video lessons. Plus you get detailed, step-by-step solutions to all practice problems, quizzes, and tests!
The next two examples will demonstrate how to solve two-step equations when the coefficient is a fraction or when you have a divisor. Let's take a look!
I know you are feeling pretty good about this, but let's keep going!
The video below will help explain the two-step process. If you are still having trouble, check it out.
Ok... one more example! This example involves an additional step before starting the two-step process.
If you have any terms in the equation that are like terms, then you will want to combine those like terms first before solving. Let's take a look....
Wow! You did it! You just applied two different rules for solving equations in order to solve two-step equations. I know you are feeling better now!

"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!"

"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!"

"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!"

"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."

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.
