Hi Roro! The answer is no, because "j" is like "h" (in English) but the "X" sounds "ks". Por example when you say "acción" the correct pronunciation is aksión. Bye, I hope to help you.

Hello! nope, its not J sounds similar like an H y Hello, and X sounds quite the same. If you say 'Exacto' in spanisht, the X will be like if you said 'Exact' in English (just ad and O and it becomes spanish :) Greetings! Alejo
