You can put this solution on YOUR website!
ax+by=c;y

This means to take the equation ax +by = c, and solve for y.

To do this subtract ax from each side of the equation:
ax+by = c
ax-ax +by = c-ax
by = c-ax

Next, since by means b TIMES y, you need to divide by b in order solve for y:
by+=+c-ax
%28by%29%2Fb+=+%28c-ax%29%2Fb
y+=+%28c-ax%29%2Fb
