Jonathan is four times Maria's age. In 3 years, he will be three times as old as Maria is then. How old is Maria now?

Respuesta :

Answer: 6 years

Step-by-step explanation:

Let Maria's age be x

Jonathan is four times Maria's age. This means that Jonathan age = 4x

In 3 years, he will be three times as old as Maria is then. This can be written as:

4x + 3 = 3(x + 3)

4x + 3 = 3x + 9

4x - 3x = 9 - 3

x = 6

Maria is 6 years
