Answer: -16n-41

Step-by-step explanation:

first, distribute 2 through the parentheses:

2(-n-3)-7(5+2n) = -2n-6-7(5+2n)

second, distribute 7 through the parenthesis:

-2n-6-7(5+2n) = -2n-6-35-14n

Collect like terms:

-2n-6-35 and -16n-6-35

Calculate the difference:

-2n-6-35-14n = -16n-41

SOLUTION:

-16n-41

y - Brazilian coffee ( in pounds );
x + y = 100
8.85 x + 3.85 y = 6.55 ( x + y )
----------------------------------------
x = 100 - y
