Question

Помогите решить задание 8.

Answer 1

1) 12-8=4
2) 12+10=22
3) 20-8=12
4) 20+10=30
5) 28-8=20
6) 28+10=38
7) 43-8=35
8) 43+10=53

Answer 2

A = 12
а - 8 = 12 - 8 = 4
а + 10 = 12 + 10 = 22

а = 20
а - 8 = 20 - 8 = 12
а + 10 = 20 + 10 = 30

а = 28
а - 8 = 28 - 8 = 20
а + 10 = 28 + 10 = 38

а = 43
а - 8 = 43 - 8 = 35
а + 10 = 43 + 10 = 53
