I tried to install a ram card on my ideapad 110-15ACL, it says I have 2 ram slots, but I only have one. Why?

I took my cover off the bottom of the laptop to install the new 4gb RAM card. I found a 4gb RAM card in there and no other slot to install my new card. My system settings tells me there are 2 slots. Where is my second slot?

It's a Lenovo Ideapad 110-15ACL. Also says 80TJ
