Pleas Help! How do आप play the पियानो when the sheets have two right hands on चोटी, शीर्ष and one left hand?

the upper part is for the voice and the pianist is to play the lower parts (they're joined on the left with this strange thing i can't name in english).

Sing the one that des have the bracket connecting it to the left hand. Im assuming this is a लोकप्रिय song, but the चोटी, शीर्ष one is for you're voice. या just discard one of the right hands

i think आप are just supossed to play the right hand at first and then the left.
