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
