Justin is 2 years older than one third marcella’s age. aimee is four years younger than 2times justin’s age. define a variable and write an expression to represent justin’s age. then find justine’s age and aimee’s age if marcella is 63 years old.

Let's assume

Marcella’s age is x

now, we are given

Justin is 2 years older than one third Marcella’s age

so, Justin's age will be

Let's assume Justin's age is J

so, we get

Aimee is four years younger than 2times Justin’s age

so,

Aimee's age will be

now, we can plug J

now, we are given

Marcella is 63 years old

so, x=63

we can plug x=63 and find A

so,

Aimee's age is 42 years

now, we can plug x=63

so, Justin's age is 23 years
