Noah visits different states every summer. This summer, he started with 2 states already visited and visits 6 states per day. Write an equation to model this situation (use d for days and s for states)

s = number of states visited

d = number of days

6d = number of states visited after d days pass by, excluding the first 2 visited

6d+2 = total number of states visited, including the 2 originally visited

Answer: s = 6d+2
