Русский Язык shouldn't be capitalized in either sentence.

Я учу Русский Язык

This can either mean "I learn the Russian language" (usually the connotation is "by memorization"), or "I teach the Russian language," in which case it's grammatically incorrect.
вообще-то "I teach (somebody) the Russian language," переводится как "Я учу (кого-то) русскому языку"
Вот то, что я сказал в отдельных словах
