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
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.
