Lesson 5: Finding mistakes in one-step equations# Finding mistakes in one-step equations

Gain a deeper understanding of solving one-step equations by studying a correct and an incorrect example.

Solving one-step equations is all about using inverse operations on both sides of an equation to get the variable by itself. Answer the questions below to deepen your understanding of how to solve one-step equations.

- If the value of x in the answer does not make the original equation true, then there’s a mistake somewhere.

This means that checking whether or not your value of x makes the original equation true greatly reduces the frequency of mistakes on homework and tests.(30 votes)

- Later in algebra, you will encounter two-step equations and then equations with more than two steps, including equations with parentheses and/or the variable on both sides. A strong understanding of one-step equations will help you solve multi-step equations later on.(11 votes)
- Tips for people that are struggling:

1) Try taking a piece of paper and do it yourself! Remember to show it step by step so you can compare your work against the problem. After you did calculated, you can see which step they messed up on and select the correct answer!

2) If you are having a hard time calculating it then try to use logic! You would look at the answers and just cross out mentally the options that just don't look and feel right. This work only sometimes so I strongly encourage the first option. And if you are having trouble calculating, then I recommend to review the lesson they taught how.

I hope this helped some of you! After you realize how it works, its so useful and so much more easier! Have a great day / night!(8 votes) - I am your question.(7 votes)
