You have to isolate the variable, so you must first separate the constants from the variable. Add 3 on both sides to cancel out the minus three and to move it to the other side. Now you have 27x=9.

The population density is approximately 4 people per square mile

<h3>Calculating Population Density </h3>

From the question, we are to determine the population density

Population density is given by the formula,

$Population\ density = \frac{Number\ of\ people}{Land\ area}$

Number of people in the town = 12620 people

Now, we will determine the land area of the town

From the given shape,

Land area of the town = (60 × 65) - (25 ×40)

Land area of the town = 3900 - 1000

Land area of the town = 2900 square mile

∴ Population density = $\frac{12620}{2900}$

Population density = 4.3517

Population density ≅ 4 people per square mile

Hence, the population density is approximately 4 people per square mile
