Question 982968
<pre>
I don't want to do your work for you, so Ill do one exactly like yours so you
can do your own problem and use the one I do as a guide.  Yours is exactly
like it.
</pre>
I add 6 to the number, multiply the result by 2, I get the same as when I add 19 to it.
<pre>
I start with 

N
</pre>
I add 6 to the number, 
<pre>
So I write + 6 after the N, now I have this:

 N + 6
</pre>
multiply the result by 2, 
<pre>
Now before I can multiply that, since there are two terms, I must
put parentheses around it, like this (N + 6), so that when I multiply
it by 2, both terms will be multiplied by 2 and not just the N only.
So now I have

2(N + 6)
</pre>
I get the same as 
<pre>
"I get the same as" means to put an equal sign after it because when
things are the same they are equal:

2(N + 6) =
</pre>
when I add 19 to it.
<pre>
Adding 19 to N was just like adding 6 to it.  We get N + 19. So you
write N + 19 after the equal sign:

2(N + 6) = N + 19

Now that's an equation.  To solve it

Distribute to remove the parentheses:

2N + 12 = N + 19

Then I get rid of the + 12 on the left by adding -12 to both sides.

2N + 12 = N + 19
    -12      -12
----------------
2N      = N +  7

Then I get rid of the N on the right side by adding -N to both sides:

     2N = N + 7
     -N  -N
     ----------
      N =     7

The answer is 7.
