Okay, maybe I just totally missed somthing somewhere, but I encountered a problem while learning "Combination of Terms Equations".(adsbygoogle = window.adsbygoogle || []).push({});

Here is how they work the problem:

6x - 2x + 6 = x -2x -16

4x + 6 = -x + 16

-6 + -6

-------------------

4x = -x + 10

+x = +x

---------------

5x = 10

5x = 10

5----5

---------------

x = 2

Now, can you explain how they did this? What happend to the '2' and where did the negitive 'X' come from, etc?? Show me how to work this please, because they don't. It seems like they're pulling numbers out of thin air. :grumpy:
