Answer: the number of social media advertisements that you purchased is 18

The number of newspaper advertisements that you purchased is 6

Step-by-step explanation:

Let x represent the number of social media advertisements that you purchased.

Let y represent the number of newspaper advertisements that you purchased.

You purchase three social media advertisements for every one newspaper advertisement. This means that

y = x/3

x = 3y

You end up purchasing a total of 24 advertisements. This means that

x + y = 24 - - - - - - - - - 1

Substituting y = into equation 1, it becomes

3y + y = 24

4y = 24

y = 24/4 = 6

x = 3y = 6×3 = 18

The equations are

x = 3y

x + y = 24
