x in (-oo:+oo)
(5*x)/4-(1/5) = 1-((2/5)*(x-(1/10))) // - 1-((2/5)*(x-(1/10)))
(2/5)*(x-(1/10))+(5*x)/4-(1/5)-1 = 0
(2/5)*(x-1/10)+(5*x)/4-1/5-1 = 0
2/5*(x-1/10)+(5*x)/4-1/5-1 = 0
(2/5*4*5*(x-1/10))/(4*5)+(5*5*x)/(4*5)+(-1*4)/(4*5)+(-1*4*5)/(4*5) = 0
2/5*4*5*(x-1/10)+5*5*x-1*4-1*4*5 = 0
33*x-20-4-4/5 = 0
33*x-20-24/5 = 0
33*x-124/5 = 0
(33*x-124/5)/(4*5) = 0
(33*x-124/5)/(4*5) = 0 // * 4*5
33*x-124/5 = 0
33*x-124/5 = 0 // + 124/5
33*x = 124/5 // : 33
x = 124/5/33
x = 124/165
x = 124/165
