Solution for 9x/3x-1-4/3x-1=4 equation: 


x in (-oo:+oo)

((9*x)/3)*x-((4/3)*x)-1-1 = 4 // - 4

((9*x)/3)*x-((4/3)*x)-4-1-1 = 0

((9*x)/3)*x+(-4/3)*x-4-1-1 = 0

3*x^2-4/3*x-6 = 0

DELTA = (-4/3)^2-(-6*3*4)

DELTA = 664/9

DELTA > 0

x = ((664/9)^(1/2)+4/3)/(2*3) or x = (4/3-(664/9)^(1/2))/(2*3)

x = ((664/9)^(1/2)+4/3)/6 or x = (4/3-(664/9)^(1/2))/6

x in { (4/3-(664/9)^(1/2))/6, ((664/9)^(1/2)+4/3)/6 }
