1.25 = 1/(1-x) // - 1/(1-x)
1.25-(1/(1-x)) = 0
1.25-(1-x)^-1 = 0
1.25-1/(1-x) = 0
(1.25*(1-x))/(1-x)-1/(1-x) = 0
1.25*(1-x)-1 = 0
0.25-1.25*x = 0
(0.25-1.25*x)/(1-x) = 0
(0.25-1.25*x)/(1-x) = 0 // * 1-x
0.25-1.25*x = 0
0.25-1.25*x = 0 // - 0.25
-1.25*x = -0.25 // : -1.25
x = -0.25/(-1.25)
x = 0.2
x = 0.2
