Answer:

n > -5

Step-by-step explanation:

<u>Step 1:  Distribute </u>

-2n - 40 < 5(6 + n) + 7n

<em>-2n - 40 < 30 + 5n + 7n </em>

<u>Step 2:  Combine Like Terms </u>

-2n - 40 < 30 + 5n + 7n

<em>-2n - 40 < 30 + 12n </em>

<u>Step 3:  Add 2n to both sides </u>

-2n - 40 + 2n < 30 + 12n + 2n

<em>-40 < 30 + 14n </em>

<u>Step 4:  Subtract 30 from both sides </u>

-40 - 30 < 30 + 14n - 30

-70 / 14 < 14n / 14

<em>-5 < n </em>

Answer:  n > -5
