Answer:
n = -9
Explanation:
Given the equation, -3(n + 5) = 12, the goal is to solve for the value of n.
Use the distributive property of multiplication, where it states that:
a(b + c) = ab + ac
Distribute -3 inside the parenthesis:
-3(n + 5) = 12
-3n - 15 = 12
Next, add 15 to both sides:
-3n - 15 + 15 = 12 + 15
-3n = 27
Divide both sides by -3 to solve for n:

n = -9
Therefore, the value of n = -9.
