Show your work and conclude with the exact phrasing "Therefore, the final answer is [answer]." where [answer] is just the final number or expression that solves the problem.

Elon Musk went to Russia to buy rockets for his plans in the early 2000's, but was unsuccessful in making a deal, so he started his own company to build rockets.
Thus, the answer is yes.
