We need to solve this so we have a positive x term on one side.

First we can subtract 3 from both sides of the inequality to get:

5x<3x-9

Next we can subtra...

We need to factorise this equation to solve it.

The first step for factorisation is to make the equation equal to zero. We can do this by subtracting x from both sides to get:

...

We will use diagrams to show this in the interactive lesson space - and also run through what key terms the examiners will look for.

As with a lot of physical geography, ...
