Answer :
If Marcella is 63, divide by 3 is 21, add 2 equals out to be 23 which is Justin's age. Then 23 multiplied by 2 is 46, subtract 4 from 46, which equals out be 42 and that is Aimee's age.:)
Marcella= 63
Justin= 23
Aimee= 42
[tex]x=63[/tex] which is Marcella's age
[tex] \frac{1}{3} [/tex] of 63 is 21 ⇔ 63÷3=21
[tex]2+21=23[/tex] which is Justins age
[tex]2(23)-4=42[/tex]
Marcella's age⇒63
Justin's age⇒23
Aimee's age⇒42
Note: I was trying to find a better way to do this but I couldn't figure it out in the top of my head so I'm sorry for the long response
