а) 3(8a-4) + 6a = 24a - 12 + 6a = 30a - 12
б) 11c + 5(8-c) = 11c + 40 - 5c = 6c + 40
в) 2(y-1) - 2y + 12 = 2y - 2 - 2y + 12 = 10
г) 16 + 3(2-3y) + 8y = 16 + 6 - 9y + 8y = 22 - y

а) 7p - 2(3p-1) = 7p - 6p + 2 = p + 2
б) -4(3a + 2) + 8 = -12a - 8 + 8 = -12a
в) 3 - 17a - 11(2a - 3) = 3 - 17a - 22a + 33 = -39a + 36
г) 15 - 5(1-a) - 6a = 15 - 5 + 5a - 6a = 10 - a
