Solution for -2x+6x+4-8=5x-7x/5x-1 equation: 


x in (-oo:+oo)

6*x-2*x-8+4 = 5*x-(((7*x)/5)*x)-1 // - 5*x-(((7*x)/5)*x)-1

((7*x)/5)*x-2*x+6*x-(5*x)-8+1+4 = 0

((7*x)/5)*x-2*x+6*x-5*x-8+1+4 = 0

7/5*x^2-x-3 = 0

DELTA = (-1)^2-(-3*7/5*4)

DELTA = 89/5

DELTA > 0

x = ((89/5)^(1/2)+1)/(7/5*2) or x = (1-(89/5)^(1/2))/(7/5*2)

x = 5/14*((89/5)^(1/2)+1) or x = 5/14*(1-(89/5)^(1/2))

x in { 5/14*(1-(89/5)^(1/2)), 5/14*((89/5)^(1/2)+1) }
