Answer 2

$a - 5 = 9 \\ a = 5 + 9 \\ a = 14$

_______________

$14 - 5 = 9 \\ \: \: \: \: \: 9 = 9$

=================================

$y - 2 = 8 \\ y = 2 + 8 \\ y = 10$

_______________

$10 - 2 = 8 \\ \: \: \: \: \: \: 8 = 8$

================================

$18 - x = 8 \\ x = 18 - 8 \\ x = 10$
