-2(x-3)+5x+7=3(4-3x)+12x-9 - problem
-2x+6+5x+7=3(4x-3x)+12x-9 - distributive property
5x-2x+6+7=3(4x-3x)+12x-9 - combine like terms
3x+13=3(4x-3x)+12x-9 - combine like terms
3x+13=12x-9x+12x-9 - distributive property
3x+13=3x+12x-9 - combine like terms
3x+13=15x-9 - combine like terms
13=12x-9 - subtract 3x from both sides
22=12x - add 9 to both sides
x=0.5454

Since the value of the function is the indeterminate form 0/0, L'Hôpital's rule applies. The ratio of derivatives of numerator and denominator is
.. x/ $\sqrt{x^{2}+3 }$
Evaluated at x=1, this is
.. 1/ $\sqrt{1^{2}+3 }$ = 1/2
