8167 streets are named Second Street and 7802 streets are named Main Street.

Step-by-step explanation:

Given,

Total streets = 15969

Let,

x be the number of streets named as Second Streets

y be the number of streets named as Main Streets

According to given statement;

x+y=15969 Eqn 1

x = y+365 Eqn 2

Putting value of x from Eqn 2 in Eqn 1

$(y+365)+y=15969\\y+365+y=15969\\2y=15969-365\\2y=15604$

Dividing both sides by 2

$\frac{2y}{2}=\frac{15604}{2}\\y=7802$

Putting y=7802 in Eqn 2

$x=7802+365\\x=8167$

8167 streets are named Second Street and 7802 streets are named Main Street.
