What is an equation? An equations says that two things are equal, it will always have an equal sign.
In fact, solving an equation is just like solving a puzzle. And like puzzles, there are things you can (and cannot) do. Here are some things you can do:

And the more "tricks" and techniques you learn the better you will get. 

After solving, you should always check that your solution really is a solution.

If you want to practice, here you have some activities:

1. Does x satisfy the equation?
2. Solve one-step linear equations.
3. Solve two-step linear equations.
4. Solve multi-step equations.
5. Solve equations involving like-terms.

To end up, you can relax with these games about math vocabulary and equations solving: practice your math vocabulary with an equation puzzle or solve one-step equations and two-step equations.

Take care.
