Claire from Worcester asked the following question: Can you help me solve this: 9k + 8 = 45 Firstly, this is an equation with one unknown quantity (k) and the rest are just numbers. So let's work on those numbers first. 9k + 8 = 45 If we subtract 8 from both sides, it will be a little tidier: 9k + 8  8 = 45  8
Now we can simply divide both sides by 9 to end up with k: k = 37 ÷ 9 = 4.11 (to 2 dp) Job done! Click on the tutorials link below to learn more about algebra. Good luck!
