Hey there!

-3(n + 4) = 9

First we’re going to distribute to make this equation to solve!

-3(n + 9)
-3(n) + (-3)(9)
-3(n) = -3n
(-3)(4 = -12

New equation:
-3 - 12 = 9

ADD by 12 on both of your sides
Like: -3n - 12 + 12 = 9 + 12
Cancel out: -12 + 12 because that gives you 0
Keep: 9 + 12 because that helps us solve for the equation

**9 + 12 = 21**

New equation:
-3n = 21

DIVIDE both sides by -3
-3n/ -3 = 21/-3
Cancel out -3/-3 because that gives you 1
Keep: 21/-3 because that gives you the value of “n”

**21/-3 = n**

Solve above and you have your result of n

Answer: n = -7

Good luck on your assignment and enjoy your day!

Ok so the equation is -3(n + 4) = 9
First use distributive property so you’ll need to multiply -3 by n and 4 so it’ll give you the new equation of
-3n + 12 = 9
Now try to get the -3n by itself so you’ll need to subtract 12 from both sides and it’ll give you
-3n = -3
Now you need to get n by itself so you need to divide -3 on both sides so it’ll give you the answer of
n = 1
