Nava is 17 years older than Edward. the sum of Navas age and Edwards ages id 29. How old is Nava?

Let Nava's age be n and Edward's age be e. We have 2 equations:

1. n = e + 17
2. n + e = 29

Substitute (1) into (2)
(e + 17) + e = 29

Group like terms:
2e + 17 = 29

Running this equation through our search engine, we get:
e = 6

Substitute this into equation (1)
n = 6 + 17
n = 23
