bit of algebra practice:
rearrange to make the subject y, also, for the first one, put in the form (x-k)(y-h)=c
<a href="http://www.codecogs.com/eqnedit.php?latex=2xy-3x-y-2=0\\ and\\ y^2 - 8y @plus; 5x - x^2 - 15 = 0" target="_blank"><img src="http://latex.codecogs.com/gif.latex?2xy-3x-y-2=0\\ and\\ y^2 - 8y + 5x - x^2 - 15 = 0" title="2xy-3x-y-2=0\\ and\\ y^2 - 8y + 5x - x^2 - 15 = 0" /></a>
