Finding Weeks for Total Distance

Jenna is training for a marathon and tracks her running distance over several weeks. The distance, in miles, that she runs in week $$w$$ can be modeled by the linear equation:

$$d = 2w + 5$$

where $$d$$ represents the total distance run at the end of week $$w$$. After how many weeks will Jenna have run a total of 29 miles?
