psymon · Answer

-17 +  3sqrt(14)x = 3sqrt(21)x + 9x
-17 = 3sqrt(21)x - 3sqrt(14)x + 9x
-17 = [sqrt(21) - sqrt(14) + 3]3x
$$x = \frac{ -17 }{ 3[3+\sqrt{21}-\sqrt{14}] }$$

I get something like this. Kinda see what i did?

anonymous · Answer

yes

psymon · Answer

Okay, awesome ^_^ Anything else you would do to that is unnecessary, so that seems like a well-simplified answer to me.

anonymous · Answer

well its not 9x its just 9

psymon · Answer

Oh xD It looks like 9x is all. Okay well then we would have instead:

$$-26 = [\sqrt{21}-\sqrt{14}]3x$$=
$$x=\frac{ -26 }{ 3(\sqrt{21}-\sqrt{14}) }$$
