Can you understand this Piano sheet music as it has more beats than the time signiture ? (Part 2)?

The notes in the right hand are actually in different voices. So if you refer to the left hand, you'll notice that the eighth notes in the right hand come in on the second beat, meaning that you hold the half note in the right hand while playing the two eighth notes, and let go of both when you play the last quarter note (but don't let go of the tied note in the left hand). Hope this helps! :)
