## Exam-Style Question on Changing the Subject## A mathematics exam-style question with a worked solution that can be revealed gradually |

Question id: 437. This question is similar to one that appeared on a GCSE Higher paper in 2017. The use of a calculator is allowed.

Rearrange the following formula to make \(d\) the subject:

$$ a = \frac{b - c}{d + e} $$Circle your answer:

$$ d=\frac{b-c}{a}-e \quad \quad d=\frac{b-c}{a+e} \quad \quad d=\frac{b-c}{a-e} \quad \quad d=e +\frac{b-c}{a} \quad \quad d=e +\frac{a-e}{b-c} $$
The worked solutions to these exam-style questions are only available to those who have a Transum Subscription. Subscribers can drag down the panel to reveal the solution line by line. This is a very helpful strategy for the student who does not know how to do the question but given a clue, a peep at the beginnings of a method, they may be able to make progress themselves. This could be a great resource for a teacher using a projector or for a parent helping their child work through the solution to this question. The worked solutions also contain screen shots (where needed) of the step by step calculator procedures. A subscription also opens up the answers to all of the other online exercises, puzzles and lesson starters on Transum Mathematics and provides an ad-free browsing experience. |
