Answer:

n = -9

Step-by-step explanation:

-10(n + 5) = 40

expand the left side

- 10*n - 10*5 = 40

-10n - 50 = 40

Add 50 to both sides

-10n = 40 + 50

-10n = 90

Divide both sides by -10

n = -9

Answer: -9

Step-by-step explanation:

-10(n+5)=40

-10n-(-50)=40

-10n-(-50)+50=40+50

-10n=90

-10n/-10=90/-10

n= -9
