Cotton is one of the most versatile textile fibres and incredibly common worldwide. Some advantages of cotton are that it is a very strong fibre and becomes stronger when wet. Cotton is naturally anti-bac...

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.
