3x + 5 = 35

In this situation, you would want to take away 5 to both sides.

3x + 5 - 5 = 35 - 5

3x = 30

Then you would want to divide both sides by 3 in order to get x on the l...

1/3 + 3/4 

First we make the denominator the same. i.e: we would multiple 1/3 by 4 and multiply 3/4 by 3 in order to get the same denominator.

4/12 + 9/12. 

Now you can add the numera...

We should begin by multiplying out the brackets. Firstly, multiply each term in the first bracket with the first term in the second bracket: x times x equals x² and -2 multiplied by x is equal ...

3:2 means there are 5 parts. So 18 litres can be divided by 5, and the price of each part worked out individuallly.

18 / 5 = 3.6

To work out how much the white paint costs: 3.6 x £2.80 = £10...

When dealing with questions to do with expanding brackets, you must multiply every term in one bracket with all the others in the second bracket. So for this question, we can see we have 4 terms in total:...
