What is Equations with Brackets and Fractions?
Within Mathematics, which covers numbers, algebra, geometry, trigonometry and statistics from first principles to exam level, this topic explains Equations with Brackets and Fractions. Maths builds step by step, so each topic here gives you a rule, a picture and a quick check you can use on homework and in exams.
Check that you can explain Equations with Brackets and Fractions in your own words and give one example from everyday life. If you can do that, you have understood the core idea.
Understanding Equations with Brackets and Fractions gives you a reliable method you will reuse in later maths units, in science lessons and in data work.
Equations with Brackets and Fractions in detail
When an equation has brackets, expand them first, then collect terms and solve. For 3(x − 2) = 12, you expand to 3x − 6 = 12, add 6 to get 3x = 18 and divide to get x = 6. Alternatively you can divide both sides by 3 first.
When an equation has fractions, multiply every term by the common denominator to clear them: for x/2 + x/3 = 10, multiplying by 6 gives 3x + 2x = 60, so x = 12. Doing the same to every term is the key to avoiding errors, and this approach prepares you for more complex algebraic fractions.
