Ответ:

$\frac{9 {a}^{2} + {y}^{2} }{3a - y} + \frac{6ay}{y - 3a} = \frac{9 {a}^{2} + {y}^{2} - 6ay }{3a - y} = \frac{ {(3a - y)}^{2} }{3a - y} = 3a - y$

$\frac{ {a}^{2} {x}^{2} + 36 {y}^{2} }{ax - 6y} + \frac{12axy}{6y - ax} = \frac{ {a}^{2} {x}^{2} + 36 {y}^{2} - 12axy}{ax - 6y} = \frac{ {(ax - 6y)}^{2} }{ax - 6y} = ax - 6y$
