Level 1  Simple equations where the solution can be found by performing one operation on both sides of the equation.
Example: \(8n = 64\)
Level 2  Simple equations where the solution can be found in two steps.
Example: \(9e + 6 = 78\)
Level 3  Equations where a multiple of the unknown and a constant are on both sides.
Example: \(4y  7 = 3y  4\)
Level 4  Equations including brackets.
Example: \(2(4r + 7)  9 = 21\)
Level 5  More complex equations requiring multiple steps to find the solution.
Example: \(6(10h + 3) + 4 = 7h + 287\)

Here is an example showing a good way to solve an equation of this type (Level 3) by thinking of the two sides of the equation as two sides of a balance. The equation will remain balanced only if you do the same thing (multiply, divide add or subtract) to both sides.
5x + 3 = 3x + 15
Subtract 3 from both sides
5x = 3x + 12
Subtract 3x from both sides
2x = 12
Divide both sides by 2
x = 6

"I am commenting to show you a wrong answer. Me, my teacher and my friends around me have been trying to solve this equation. We believe that you have your answer wrong and you may need to check it. The question is:
2(4y3)=5(y+6)
If you worked out the answer you would know that y=12. Unfortunately, when I submitted that answer, it was wrong. I hope you take this into consideration and I hope I will not find any more problems that I believe are wrong.
Your sincerely,
Henry J. Spencer."

"Thanks Henry for pointing out the error with Level 5 question 2. It has now been corrected. The questions that you see are drawn from a database containing a number of different versions of the question type. One of the versions is chosen each time the page is loaded. I hope you will not find any other errors but please let me know if you do. I am very grateful for the time you took to flag up the mistake. Thank you again."

"This resource is absolutely incredible. So useful. Just enough questions. Just enough challenge. Gives the students control about which level they would like to attempt. And it selfassesses, too!"
