Answer 2

Answer:

36

Step-by-step explanation:

We know that n + 21 = 57 so n has a value that satisfies this equation, we can use algebra to support our thinking:

First I have laid out my equation:

1. $n + 21 = 57$

Then I subtracted 21 from 57 to isolate the n

2. $n = 57 - 21$

And the final value is 36

3. $n = 36$
