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. You'll even find a couple of video lessons to help guide you through this process.
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.
Just in case you are still confused, we'll look at another example similar to this one. Remember to focus on how there are two steps that are used in order to find the solution to this equation.
For more clarification on example 2, take a look at the following video...

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!
