You can put this solution on YOUR website!
Separately.
You can only add/subtract like things.
Here's an example.
%2812%2B10x%29%2B%2844x-13%29=12%2B10x%2B44x%2B%28-13%29
%2812%2B10x%29%2B%2844x-13%29=12%2B%28-13%29%2B10x%2B44x
%2812%2B10x%29%2B%2844x-13%29=%2812%2B%28-13%29%29%2B%2810x%2B44x%29
%2812%2B10x%29%2B%2844x-13%29=%28-1%29%2B%2854x%29
%2812%2B10x%29%2B%2844x-13%29=-1%2B54x
or
%2812%2B10x%29%2B%2844x-13%29=54x-1
