Question

Alfonso is 8 years older than Ashley. Five years ago Alfonso was three times as old as Ashley. How old is Ashley now?

Answer 1

Answer:

Ashley is 9 years old now and Alfonso is 17.

Step-by-step explanation:

Age of Ashley = x

Age of Alfonso = x + 8

Age of Ashley five years ago =  3 * (x -5)

Age of Alfonso five years ago = (x + 8) - 5

Let's solve for x using the following equation:

(x + 8) - 5 = 3 * (x -5)

x + 8 - 5 = 3x - 15

x + 3 = 3x - 15

x - 3x = - 15 - 3

-2x = - 18

x = -18/-2 = 9

x = 9 ⇒ x + 8 = 17

Ashley is 9 years old now and Alfonso is 17.

Answer 2

Answer:

9 year old

Step-by-step explanation:

Let suppose

Alfonso = x

Ashley = y

x = 8 + y

Five years ago Alfonso was three times as old as Ashley

x - 5 = 3 (y-5)

put value of x

y + 8 - 5 = 3y - 15

y + 3 = 3y -15

2y = 18

Ashley = y = 9
