So first, we must distribute to get rid of the parentheses. This will give us:
[tex]3x-24=15[/tex]
We want to get x on one side by itself. It is important to remember, however, that what we do to one side, we must do to the other side. So let's add 24 to both sides:
[tex]3x=39[/tex]
Then we want to divide by 3 on both sides to give us x alone. Let's solve:
[tex]x=13[/tex]
So now we know that in this equation, x = 13.
[tex]3x-24=15[/tex]
