<PRE><B>Question 656154</B>
Assume Dinos age now  is y

12 years ago   Dinos age y-12


8 times of that 8*(y-12)

in 30 years Dinos age y + 30 


The equation will be 
y + 30 = 8*(y-12) 

y + 30 = 8y -96

y - 8y = -126 

-7y = -126 

y = -126/-7 = 18 


Since y is the Dinos age now 

Dino is 18 years old
