Let Amanda's age = x.
Gregory's age = x + 5.

Since Gregory is 17 years old.
17 = x + 5
x = 17 - 5
x = 12

Amanda is 12 years old.

Amanda`s Age.

Amanda=x

Gregory`s Age.

Gregory=17 yrs.

Equation formation.

1/3× x = (1/3 x)

1/3 x + 5 = 17

Equation= 1/3 x +5 =17

1/3 x = 17-5

1/3 x = 12

x=12×3

x=36

Amanda`s age = 36
