10a-(5a-3(4x+7(8a-x))-19x)-9x = 10a - (5a - 3(4x+56a-7x) - 19x) - 9x = 10a - (5a - 12x - 168a + 21x - 19x) - 9x = 10a - 5a + 12x + 168a - 21x + 19x - 9x = 173a -x

 
33b-(-80b+5(5b-6(11a-3b))+300a)-30a = 33b - (80b + 5(5b - 66a + 18b) + 300a) - 30a = 33b - (80b + 25b - 330a + 90b + 300a) - 30a = 33b - 80b - 25b + 330a - 90b - 300a - 30a = -162b
