Answer:
n ≥ -12
Step-by-step explanation:
Change the less than or equals sign to an equals sign
-7(n+7) = 35
Use distributive property to figure out what -7(n+7) equals
-7n-49 = 35
Add 49 to both sides
-7n = 84
Divide both sides by -7
n = -12
Bkuz you want n -7(n+) to be less than or equal to 35 you have to change the equals sign in n = -12 to a greater or equal to sign
Hope this helps!
