Question

–(c + 5) + 2c = =

3(6 – m) – 10 = =

–(–4x – 3) – 4x = =

3a – (4 + 2a) = =

Пожалуйста срочноооооо!!!!!!!

Answer 1

Ответ:

1) –(c + 5) + 2c = c-5+2c=3c-5

2) 3(6 – m) – 10 = 18-3m-30 = -3m-12

3) –(–4x – 3) – 4x = 4x+3-4x=3

4) 3a – (4 + 2a) = 3a-4-2a=a-4

Answer 2

1) c-5
2)=8-3m
3) =3
4) a-4
