Answer 1

Answer:

-21

Step-by-step explanation:

I used the backward method

She adds 8 to get 5.

So we start with 5 and subtract 8

5-8 = -3

She divides by 7 but since we are using the backwards method, we have to multiply.

-3*7= -21

After that, we can check our answer

Krutika was thinking of -21

-21/7= -3

-3+8= 5

-21 is the answer

Hope this helps!
