 How do we solve equations that involve fractions? Before we get started, I'm assuming you already know how to solve equations by balancing. You must do the exact same thing to both sides. If you're unsure, you may want to watch this video first. So let's have a look at how to solve equations involving fractions. The whole of 2f plus 8 has been divided by 3. We need to move this 3 first so that everything is on the same level, no denominators. So multiply both sides by 3. And the times by 3 and divide by 3 cancel on this side, leaving us with a simple linear equation to solve. Easy! And as always, check your answer, substitute f is 5 into the original question. 6 equals 6. f is 5 is correct. For this one, we want to start by multiplying up the 2. But we need to multiply the whole of this side by 2. So put brackets around it. Then you just expand the brackets and carry on as normal. Here's one for you to do. Pause the video, solve for g and click play when you're ready. How did you get on? Did you get g equals negative 4? And as always, double check your answer. So that's how we solve equations involving fractions. Start by multiplying up the denominator that it's all on the same level. And then carry on as normal. Remember to always do the same thing to both sides. And you'll never make a mistake. Then check your answer at the end.
