1) n-(23-n)+(-n+ 35)
2) 7m+ 9p-16m - p
3)-9(5+ a)+6(a - 7)​

Answer 1

Ответ:

1) n-(23-n)+(-n+ 35)=n-23+n-n+35=n+n-n-23+35=n+12

2) 7m+9p-16m-p= 7m-16m+9p-p= -9m-8p

3)-9*(5+a)+6*(a-7)​= -45-9a+6a-42= -45-42-9a+6a= -87-3a

Answer 2

1) n-(23-n)+(-n+ 35)=n-23+n-n+35=n+12

2) 7m+9p-16m-p= 7m-16m+9p-p= -9m-8p

3) -9(5+ a)+6(a - 7)​=-45-9a+6a-42=-87897-3a
