I took a long shot on eliminating the natural log term so I set y^2 + 2x = 1. The ln didn't fit the other bases so I figured it was worth a try. These types of equations are always fudged. In the end it was a good idea.

That led to 1) ln(1) = 0 and 2) 4x = 2 - 2y^2 and it was a piece of cake from then on.

x = 0 and y = -1

I've just sent a friend request( Nguyen Minh) btw I saw your post. Thanks. I am 13

Sorry for not being able to solve this, it's national level shit lol im just 17

However one of my acquaintances has pulled this off, add me on facebook and I'll send you his solution

https://www.facebook.com/quangchieens/I've just fixed it. Thanks for noticing that. And yes, mình là người Việt. Nếu đc thì giải hộ mình nhé.

wait isn't the number 1 at the end of the first equation a little bit wrong?

are you from viet nam?
