Sergio believes he is five years younger than double the age of Chloe and Chloe believes she is five yearsolder than half of Sergio's age. Are they both right?

Respuesta :

Let S represent Sergio's age

Let C represent Chloe's age

Sergio believes he is five years younger than double the age of Chloe. This would be expressed as

S = 2C - 5

Chloe believes she is five years older than half of Sergio's age. This means that

C = 5 + S/2

If we multiply the second equation by 2, it becomes

2C = 10 + S

This means that both equations are not the same. Therefore, they are not right
