-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
