abc = 2 x -5 x 0.5= -10 x 0.5= -20 / 2= -10
2d+10c= 2(-20) + 10(0.5)= - 40 + 5= -35

First use the gradient equation for a line: difference in y over difference in x:dy/dx = gradienttherefore: (15-9)/(d-5) = 315-9=3(d-5)6=3d-1521=3dtherefore d = 7

Call '5x + y = 21' equation 1 and 'x - 3y = 9' equation 2. To solve this, we need the coefficients of x in both equations to be the same or the coefficients of y in both equations to be the same.

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
