4) determine a value for a number, n, that makes the following statements true
3.876 +n is greater than 4.424
and 3,876 - n is greater than 3,326

Step-by-step explanation:

3.876 + n > 4.424          subtract 3.876 from both sides

3.876 - 3.876 + n > 4.424 - 3.876

3,876 - n > 3,326            subtract 3,876 from both sides

3,876 - 3,876 - n > 3,326 - 3,876

-n > -550            change all signs

faster, im not sure why but i know it is faster
