Edexcel GCSE Maths Spec B – Modular: Booster C © Pearson Education This document may have been altered from the original. The key thing is to write down everything you find out as and when it comes up in the question.

Edexcel GCSE Maths Spec B – Modular: Booster C © Pearson Education This document may have been altered from the original. Think about this example: I think of a number. My number is x. If I add 3 to the number and then multiply the result by 4 I get the same answer as I would get if I multiplied my number by 2 and then added 3. What is my number?

Edexcel GCSE Maths Spec B – Modular: Booster C © Pearson Education This document may have been altered from the original. Think about this example: I think of a number. My number is x. If I add 3 to the number and then multiply the result by 4 I get the same answer as I would get if I multiplied my number by 2 and then added 3. What is my number? All you need to do is think about each section in turn.

Edexcel GCSE Maths Spec B – Modular: Booster C © Pearson Education This document may have been altered from the original. Think about this example: I think of a number. My number is x. If I add 3 to the number and then multiply the result by 4 I get the same answer as I would get if I multiplied my number by 2 and then added 3. What is my number? So write down x.

Edexcel GCSE Maths Spec B – Modular: Booster C © Pearson Education This document may have been altered from the original. Think about this example: I think of a number. My number is x. If I add 3 to the number and then multiply the result by 4 I get the same answer as I would get if I multiplied my number by 2 and then added 3. What is my number? So add 3.

Edexcel GCSE Maths Spec B – Modular: Booster C © Pearson Education This document may have been altered from the original. Think about this example: I think of a number. My number is x. If I add 3 to the number and then multiply the result by 4 I get the same answer as I would get if I multiplied my number by 2 and then added 3. What is my number? Double the result.

Edexcel GCSE Maths Spec B – Modular: Booster C © Pearson Education This document may have been altered from the original. Think about this example: I think of a number. My number is x. If I add 3 to the number and then multiply the result by 4 I get the same answer as I would get if I multiplied my number by 2 and then added 3. What is my number? Use equals for this.

Edexcel GCSE Maths Spec B – Modular: Booster C © Pearson Education This document may have been altered from the original. Think about this example: I think of a number. My number is x. If I add 3 to the number and then multiply the result by 4 I get the same answer as I would get if I multiplied my number by 2 and then added 3. What is my number? ‘Same answer’, so equal.

Edexcel GCSE Maths Spec B – Modular: Booster C © Pearson Education This document may have been altered from the original. Now solve the equation, showing your working. Expand brackets. Subtract 2x from both sides. Subtract 12 from both sides. Divide both sides by 2.
