Solution for 10x/5x-1=5+2/5x-1 equation: 


x in (-oo:+oo)

((10*x)/5)*x-1 = (2/5)*x-1+5 // - (2/5)*x-1+5

((10*x)/5)*x-((2/5)*x)-5-1+1 = 0

((10*x)/5)*x+(-2/5)*x-5-1+1 = 0

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

DELTA = (-2/5)^2-(-5*2*4)

DELTA = 1004/25

DELTA > 0

x = ((1004/25)^(1/2)+2/5)/(2*2) or x = (2/5-(1004/25)^(1/2))/(2*2)

x = ((1004/25)^(1/2)+2/5)/4 or x = (2/5-(1004/25)^(1/2))/4

x in { (2/5-(1004/25)^(1/2))/4, ((1004/25)^(1/2)+2/5)/4 }
