the population in new york is about 18.8 million people this is about 9.9 milion more poeple than the population in chicago write and soleve an equation to find the approximate population in chicago

Let's denote the population in Chicago as "C".

According to the given information, the population in New York is about 9.9 million more than the population in Chicago. So, we can write the equation as:

18.8 million = C + 9.9 million

To find the approximate population in Chicago, we need to solve this equation for C.

Subtracting 9.9 million from both sides of the equation:

18.8 million - 9.9 million = C

8.9 million = C

Therefore, the approximate population in Chicago is 8.9 million people.
