Adele is 5 years older than timothy. in three years, timothy will be 2/3 of adeles age. what is adeles current age?

A=5+t
t+3=2/3(a+3)
sub 5+t for a
t+3=2/3(5+t+3)
t+3=2/3(t+8)
times 3 both sides
3t+9=2(t+8)
3t+9=2t+16
minus 2x both sides
t+9=16
minus 9 both sides
t=7
a=5+t
a=5+7
a=12

adele=12

The scale factor of what ?

With a continuous thought process.
