To solve for this, if our equation is:
-3(n-2) = 12
Then we must use the distributive property.
The distributive property allows us to multiply the outside number/variable by all inside numbers/variables.
It will look like this:
-3(n) + -3(-2)
-3n + 6 = 12 is our new equation.
To solve for n, we need to get -3n by itself and then simplify.
Subtract 6 from both sides.
-3n = 6
Divide both sides by -3 to get n.
n = -2
I hope this helps!
