2 a. (–6) + (–7) + = –21 b. + (–7) + 1 = –12

3 a. 10 + + (–3) = 14 b. (–9) + (–3) + = –12

4 a. 4 + (–2) + = 8 b. (–8) + + 1 = 0

5 a. + (–5) + (–5) = –4

b. 1 + (–5) + = –7​

Answer 1

Answer:

Step-by-step explanation:

Answer 2

Answer:

=> -9 + 7 + 7 = 5

=> 3 + (–4) + 10= 9

=> (–6) + (–7) + -(8)= –21

=> - 6 + (–7) + 1 = –12

=> 10 + 7 + (–3) = 14

=> (–9) + (–3) + 0 = –12

=> 4 + (–2) + 6 = 8

=> (–8) + 7 + 1 = 0

=> 6 + (–5) + (–5) = –4

=> 1 + (–5) + (-3)= –7
