yemek yapacaktým ama iþim çýktý

 I think this is spelled wrong.   It literally means.

"I would have cooked food  (dinner) but my job left"   But I am fairly sure they must of have meant.

"I would have cooked food  (dinner) but I left for my job"

 Spelling is OK.

iþim çýktý is an idiom. It means "something cropped up", or "something that I had to do happened".
