Solution for 7/3x+1-27x/3x-1=-9 equation: 


x in (-oo:+oo)

(7/3)*x-(((27*x)/3)*x)-1+1 = -9 // + 9

(7/3)*x-(((27*x)/3)*x)-1+1+9 = 0

(7/3)*x-9*x^2-1+1+9 = 0

7/3*x-9*x^2+9 = 0

DELTA = (7/3)^2-(-9*4*9)

DELTA = 2965/9

DELTA > 0

x = ((2965/9)^(1/2)-7/3)/(-9*2) or x = (-(2965/9)^(1/2)-7/3)/(-9*2)

x = ((2965/9)^(1/2)-7/3)/(-18) or x = ((2965/9)^(1/2)+7/3)/18
