Question

Помогите решить плиз !!!!

Answer 1

1. 1) 4(x-8)=4x-32
2) 8(x+3)=8x+24
3) (7-x)•8=56-8x
4) (4a-c)•12=48a-12c
5) 9 (3a-7b+8c)= 27a-63b+72c
6) (5x+8y-3k)•12=60x+96y-36k
2. 1) 3x +11x=14x
2) 25y-14y=11y
3) 28a+a=29a
4) 89m-m=88m
5) 8x+12x+21x=41x
6) 26y+38y-42y=22y
7) 13k+42k-14=55k-14
8) 84b-b+18=83b+18
9) 64c+12c-14c-28c=34c
