Students are often particularly concerned by unseen poems and the reason is obvious; you've spent months annotating your anthology booklets, drawing together comparisons and remembering a whole range of t...

First, we gather like terms: 7x + 5x = -42 - 6 This gives: 12x = -48Now we can divide both sides by 12 to solve for x: 12x/12 = -48/12This gives: x = -4

To solve simultaneous equations we need to make either the y coefficients or the x coefficients equal so that we can cancel them out. For this set of equations we are going to make the x coefficients the ...

e^ln(2x-3) = e¹
2x-3 = e
x = (e+3)/2
