Question

The geographic areas of California and the U.S. are 1.637×10^5 and 3.794x10^6 sq. mi., respectively. California’s population (as of 2012) is approximately 3.804×10^7 people. The actual population of the U.S. (as of 2012) is approximately 3.14×10^8 . How does the population density of California (i.e., the number of people per square mile) compare with the population density of the U.S.?

Answer 1

2x + 6 = 4x/2 + 12/2

To solve this, we need to transpose like terms to the same side.

2x - 4x/2 = 12/2 - 6

2x - 2x = 6 - 6

0 = 0

Since both sides are zero, it means that the equation has infinite number of solutions.
