Question

помогите пожалуйста срочно !!​

Answer 1

Ответ:

$1)2(3n - 2) - 5m - 1 = 6n - 4 - 5m - 1 = 6n - 5m - 5$

$2)(4n + 9) - (n - 6) = 4n + 9 - n + 6 = 3n + 15$

$3)6 - a + 2(3a - 1) = 6 - a + 6a - 2 = 5a + 4$

$4)(3m - 2) - (m + 4) = 3m - 2 - m - 4 = 2m - 6$

$5)5 + b + 6(2b - 1) = 5 + b + 12b - 6 = 13b - 1$

$6)(7b + 4) - (b - 4) = 7b + 4 - b + 4 = 6b + 8$
