One way in which Wells uses language to portray the narrator's sentiment about new people is by certain literary devices such as pathetic fallacy and alliteration. The narrator describes the 'warm air' ar...

Firstly expand the brackets due to BIDMAS.6x-10=7Now we want to have x on its own side, so add 10 to both sides.6x=17Finally we want to solve to find x, so divide both sides by 6.x=17/6

We should start by looking for the highest common factor of the 2 numbers involved in the equation (3&12)If you cannot do this immediately in your head, create a factor tree or list the factors3: 312:...
