Answer:

-16n - 41

Step-by-step explanation:

To simplify the equation, you need to get rid of the parentheses by multiplying the numbers outside the parentheses to the numbers inside. Then, you can combine the similar terms.

2(-n - 3) - 7(5 + 2n)                         <---- Original equation

-2n - 6 - 7(5 + 2n)                           <---- Expand first parentheses by mult.

-2n - 6 - 35 - 14n                            <---- Expand second parentheses by mult.

-16n - 6 - 35                                    <---- Combine terms with "n"

-16n - 41                                          <---- Combine whole numbers
