3x+12 (because we use distributive property) > x-2
2x>-14
X> -7

Ok so our problem is..

 3(x+4) ≥  x - 2

First, we have parenthesis. We will take care of them by using Distributive property.
So..
 3(x+4) ≥  x - 2
will become..
3x+12 ≥ x-2

Next, we shall subtract the 12 on both sides..
We will use our new equation..
3x+12 ≥ x-2
3x-12      -12
-------------
3x ≥ x-14

Now we will subtract the 'x' on both sides.
We will use our new equation..
3x ≥ x-14
-x   -x
---------
2x ≥ -14

Now we will divide the 2 on both sides.
We will use our new equation..
2x ≥ -14
2x/2 ≥ -14/2
x ≥ -7
