In 2003, the population of an African country was about 15.5 million people, which is 2 million more than 3 times the population
Contact [7]

Answer:

Equation to be solved:      2+3x=15.5

The solution we want is:   4.5 million

The solution for p is:          p=4.5

Step-by-step explanation:

The problem says:

15.5 million is 2 million more than 3 times the population in 1950.

We can write this as an equation like this:

15.5 million = 2 million       +           3(x million).

Each term contains the factor of million so if we divide both sides by a million the equation can actually be written as:

15.5            =2                    +           3(x)

15.5           =2                     +           3x

So the equation we need to solve is:

15.5=2+3x

We want to isolate 3x. To do this we need to subtract 2 on both sides:

15.5=2+3x

-2    -2

-----------------

13.5=    3x

Divide both sides by 3:

13.5/3 = 3x/3

Simplifying both sides gives:

4.5=x

So 4.5 million is the population in 1950's.
