Question #4203

When luke, the new kid, asked how old Annabelle was, she replied, "in two years, i'll be twice as old as i wa five years ago." How old is Annabelle?

Expert's answer

Let x be the age of Annabelle.

Then

x+2 = 2(x-5).

Hence

x+2 = 2x-10,

x=12

Then

x+2 = 2(x-5).

Hence

x+2 = 2x-10,

x=12
