Algebra is a part of KS3 Maths which you'll need to understand. In this quiz you'll be looking at equations (a key part of algebra) with brackets. You'll have to work out the value of x (or other letters such as a or b) by moving around letters and figures. It serves as an introduction to equations and should help you to understand them.
The key to solving equations is to keep them balanced. Imagine an old-fashioned set of weight scales, with the equal sign being the pivot in the middle. If you remove something from one side the scales will tip, unless you also remove it from the other side. You are aiming to reduce everything so that the variable is on one side of the equal sign, and the numbers are on the other. That should allow you to find their values.
As you progress through the quiz, you get a chance to solve some equations - lucky you! Take your time and see if you can get all ten questions correct.
