Answer:
Justin is 23 years old, and Aimee is 42 years old.
Step-by-step explanation:
Let Marcella's age be represented by x, and Justin's age by t.
Given that Justin is 2 years older than one third Marcella's age.
t = [tex]\frac{1}{3}[/tex] x + 2
t = [tex]\frac{x}{3}[/tex] + 2 ........... 1
Also, Aimee is four years younger than 2 times Justin's age.
Aimee = 2 x t - 4
Aimee = 2t - 4 .......... 2
But, Marcella's age is 63 years, so that from equation 1;
Justin's age = [tex]\frac{x}{3}[/tex] + 2
= [tex]\frac{63}{3}[/tex] + 2
= 21 + 2
= 23
Justin is 23 years.
From equation 2,
Aimee = 2 x 23 - 4
= 46 - 4
= 42
Aimee is 42 years.
Therefore,
Marcella is 63 years old, Justin is 23 years old, and Aimee is 42 years old.
