"есть" (pay attention, its written with "ь" at the end) is a form of the verb "быть" (to be). But could be translated not exactly word to word. Example:"У меня ЕСТЬ машина" - Literally its something like - "By me IS a car". Sounds silly, its not correct translating, but just to show u the verb "есть" ("is"). The actual meaning is "I´ve got a car". So, when u see "У меня есть...", "У него есть...", this means "I have...", "He has..." etc. (sorry if u already know this, just in case) Ur example is not bad "У Вас вопрос - У меня ЕСТЬ ответ". When u write the word with all capitals (showing, that it matters), it would be translated as "U´ve got a question - I DO have the answer". The stress is on the fact, that u HAVE the answer, but not that u have THE answer. I dont really know, how to emphasize exactly this in Russian, we dont have articles...

It's correct but for me better to write: "У Вас есть вопрос? У меня есть ответ!" Such phrases are used commonly enough.

To convey the meaning you want to, it's better to say it this way: У вас есть вопросы. У меня есть ответы на них.

Вы можете написать его на русском)))) :-)

Yes, it's OK у вас вопрос у меня естЬ ответ But it's better if you use ЕСТЬ in first part or don't use it at all or use it in both parts: у вас ЕСТЬ вопрос у меня ответ or у вас вопрос у меня ответ or у вас ЕСТЬ вопрос у меня ЕСТЬ ответ Russians don't pay attention to the (this) or a (any, one) But if you want to say tha you have a right answer to this question, you have to say: у вас ЕСТЬ вопрос у меня ЕСТЬ ВЕРНЫЙ ответ you can use ЕСТЬ or not, it doesn't matter (ЕСТ means "eats", ЕСТЬ means "is")
