How to display duplicates derivatives in the same row

My title is a bit blurry, but I can't find more correct description.
I have two columns with related data. In column A I have numbers that could appear mutiple times and in column B each number has a corresponding text value. What I want to get is only unique numbers in column A and all corresponding text values from column B to appear on the same row, but in different columns, like this:

What I have:
1.jpg


What I want:
2.jpg

How could this be done with a formula?

Here's a template to get you started. Two key things to remember:

1. Adjust cells for range references in the equations to ensure all your data is being captured.
2. The equations are ARRAYS, which means after you type the equation, do not JUST hit enter, you MUST hit CTRL+enter. If the equation isn't surrounded by {}, then you didn't hit ctrl+enter.
