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...
