Question

Justin is 2 years older than one third marcellas age. aimee is four years younger then 2 times Justins age.Define a variable and wrute an expression to represent justins age. The. Justins age and Aimees age if Marcella is 63 years old

Answer 1

J=justin
marcella=m
aimee=a

j is 2 older than 1/3 of m
'of' means multiply
j=2+1/3m

a is 4 younger than 2 times j
a=-4+2j

represent justin's age?
dunno



ok so I can solve if I know m=63
j=2+1/3m
j=2+1/3(63)
j=2+21
j=23
subsitute
a=-4+2j
a=-4+2(23)
a=-4+46
a=42

justin is 23 and aimee is 42 if marcella is 63
