Below is an instruction that describes a task. Write a response that appropriately completes the request in Swahili. Please answer in Swahili.

### Instruction:
It was reported that 2000 cases of Coronavirus had been confirmed in the state of New York in May 2020. There was half the number of cases in California, which had 400 more cases than the state of Texas. What's the total number of cases that had been confirmed in all of these states?

### Response:
 Ikiwa kulikuwa na nusu ya idadi ya kesi katika California kama New York, basi kulikuwa na kesi 2000/2 = <<2000/2=1000>>1000 za Coronavirus katika California.
California ilikuwa na kesi 400 zaidi kuliko jimbo la Texas, maana yake kulikuwa na kesi 1000-400 = <<1000-400=600>>600 za Coronavirus katika Texas.
Jumla ya kesi katika majimbo haya yote ni 2000+1000+600= <<2000+1000+600=3600>>3600.
