- This type of question is usually solved by substitution – making everything ‘x’ or ‘y’
- Once you’ve got an equation it’ll need solving
- Sometimes it involves using fractions …
- Always work down the page
- Put the equals sign in the middle
- Show any calculations on one side of the paper
- Is your answer reasonable? If not, go back and check, if you have time ….
