distribute the 9 to everything inside the ()
9x+54=-3x-6
+6 +6
9x+60=-3x
-9x -9x
60=-12x
divide by -12 on both sides
and get...
x=5

first you multiply the 9 into the bracket...
9(x+6) = -3x - 6
9x+54 = -3x -6
then.. you add the 3x to the 9x and subtract 54 from -6
9x + 54 = -3x -6
12x = -60
then...you divide -60 by 12
12x = -60
x = -60/12
then put it to the lowest common denominator
x= -60/12
x= -5

9(x+6)= -3x-6 You multiply 9 times x and get 9x, then multiply 9 x6 and get 54 you end \ with
9x + 54= -3x-6 you then add 3x to each side
9x+3x+54 =3x-3x-6 which leaves you with
12x +54 = -6 then subtract 54 from both sides
12x +54-54 =-6-54 which leaves you with
12x=-60 you then divide both sides by 6
12x/6=-60/6 which leaves
x=-5
I blew it the first time around I had to look at one above mine to realize I made a mistake and I had to correct mine

Let's start by getting rid of the parenthes by multiplying the (x+6 to get 9x + 54.
Your new equation is 9x+54= -3x-6
Let's subtract the 54 from both sides
9x=-3x-60
Now add 3x to both sides
12x=-60
To get the x by itself, you will need to divide both sides by 12.
x=-5

9[ x + 6]= -3x-6
1. do distributive property:
9x+ 54= -3x-6
2. add 6 to get the answer alone:
9x+54=-3x
3. whatever you do to one side you have to do to the other:
9x+60= -3x
4. bring the variables on one side:
60= -12x
5. divide the numbers:
60 divided by -12: 5
-12x divided by -12: x
6. X=5
7. Check answer
