Question

Bob thinks of a number. He subtracts 5 from the number and then adds 7 to the

result. The final result is -20. What is the original number?

Answer 1

The answer to this is 18.

Explanation:

Let's see if it's 18. To do this, we must subtract five and add seven to it.

18 - 5 = 13

After we subtract, we add the seven.

13 + 7 = 20.

I hope this helps!
