ok so far I have 12y=3y-3

hero · Answer

You're supposed to cross multiply

hero · Answer

5(3y - 8) = 12y

hba · Answer

@CaveDucks How did you get that ?

anonymous · Answer

Ohhh okay I was cross multiplying wrong. If that's even possible lol. 
So now I have 15y-3=12y.

hero · Answer

What's 5 x 8 ?

anonymous · Answer

40

hero · Answer

Okay, so when you DISTRIBUTE on the left side you're supposed to get:

5*3y - 5*8 = 12y

anonymous · Answer

ohh okay so i messed up where i did 5*-8

hero · Answer

Okay, so finish it correctly

anonymous · Answer

I got 13y at the end. i subtracted 15y from both sides and came out with -40=-3y and divided them both by -3 which came out with 13.333(a bunch of 3s) so I assumed it was 13y

hero · Answer

5(3y - 8) = 12y
15y - 40 = 12y

That's what you were supposed to get afterwards

Then you put like terms on the same side using inverse operations:
15y - 12y = 40
3y = 40
  y = 40/3

You don't need to go any further than that since it is the most exact form to express the answer.

Ohhhh I was doing it completely wrong. Thank you for explaining it to me and helping me :)
