Respuesta :

Answer:

Step-by-step explanation:

William's present age = x

William 15 years from now = x + 15

William 5 years ago = x - 5

William says that 15 years from now, his age will be 3 times his age 5 years ago.

x + 15 = 3(x-5)  ← equation formed

x + 15 = 3x - 15

3x - x = 15 + 15

2x = 30

x = 15 . ← William's current age

William is 15 now
