Work from the inside out,

2y%2B%287%283%282y-5%29-%288y-7%29%29%2B9%29=2y%2B%287%286y-15-8y%2B7%29%29%2B9%29
2y%2B%287%283%282y-5%29-%288y-7%29%29%2B9%29=2y%2B%287%28-2y-8%29%29%2B9%29
2y%2B%287%283%282y-5%29-%288y-7%29%29%2B9%29=2y%2B%28-14y-56%29%2B9%29
2y%2B%287%283%282y-5%29-%288y-7%29%29%2B9%29=-12y-56%2B9%29
2y%2B%287%283%282y-5%29-%288y-7%29%29%2B9%29=-12y-47%29
