Justin is 2 years older than one third marcella's age
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
\(x=63\) which is Marcella's age
\(\frac{1}{3}\) of 63 is 21 ⇔ 63÷3=21
\(2+21=23\) which is Justins age
\(2(23)-4=42\)
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
