First step...rewrite the left side like this..since 8 is just 2^3
$$2^{3(y-2)}=2^{y}$$

anonymous · Answer

Now you can just set 3(y-2) = y since you have the same base (2) on both sides

anonymous · Answer

You shouldn't get -3

anonymous · Answer

i dont understand this

anonymous · Answer

You dont know what to do next? Or you don't understand one of my steps?

anonymous · Answer

your steps actually helped me but i dont understand what to do next i would ask my teacher but she gets mad when i ask her to explain things to me

anonymous · Answer

Like I said a few lines up, just solve 3(y-2) = y|dw:1376066345277:dw|
