Ach, I see what I did wrong. Had myself worried there for a minute. I’m going to bed.

3-4x = 6X+13
Didn't we just have this a few days ago?
3-4x = 6x+13
-4x-6x =13-3
-10x = 10
x = 10/-10
x = -1

When my eldest was in 7th grade I decided to go to a nearby college and take a college math class so that I could remember everything I had long forgotten , I was never sorry I did that ...

If I were you, I’d go the long-way round using an Inverse Matrix with Gauss-Jordan Elimination. It’s much more fun that the solutions proposed by others.
To: Drango
In a similar vein...

That Khan academy is great! Thanks for the link!
Just got done watching the video on Partial Fraction Expansion (now I really feel like a nerd, but I’m smarter!).

I've done all the algebra and trig and now into calculus.
It is so much better when you are older and know how it applies to life.
BTW, I hear Khan is going to produce a huge, comprehensive effort aimed at computer programming...stay tuned!

Another point. Kahn says that everyone is good at math...some people just have poor teachers.

LOL. Much better that you found it than having someone else point it out.
