You can put this solution on YOUR website!
first I want to say your the first student Ive come accross to put your question in corrct source format. So thank you.
4%2F%282x-6%29-12%2F%284x%2B12%29=12%2F%28x%5E2-9%29
4%2F%282%28x-3%29%29-12%2F%284%28x%2B3%29%29=12%2F%28%28x-3%29%28x%2B3%29%29

2%28x%2B3%29-3%28x-3%29=12
2x%2B6-3x%2B9=12
15-x=12
15-12=x
3=x
x=(3,-3)
