You are dealing with an algebraic expression. So, the most important thing to remember is, do the same thing to both sides. You distributed the 3 correctly into the parentheses. Now you have
3x+15=4x
now you need to get 1x on one side of the equal sign, and the numbers on the other side.
I would subtract 3x from each side. It cancels itself out, and you are left with 15 on one side, and when 3x is subtracted for 4x you get 1x.
15=1x
which is the same as
x=15

Then after 3x+15=4x you must put the 3x to the other side.
So subtract 3x from the left side of the equation and subract 3x from the right side of the equation.
You will be left with x=15

You then minus 3x to both sides
so that gives you 15=1x
then divide 1x on both sides
and you get x=15
Happy to help! : )

Then you get all the x terms on one side of the equation by adding/subtracting, and then divide the equation by the x coefficient.
