0.25*(2*x+1)-(1/x)-1 = x/2 // - x/2
0.25*(2*x+1)-(x/2)-(1/x)-1 = 0
0.25*(2*x+1)-(x/2)-x^-1-1 = 0
0.25*(2*x+1)-x/2-1/x-1 = 0
(0.25*2*x*(2*x+1))/(2*x)+(-x*x)/(2*x)+(-1*2)/(2*x)+(-1*2*x)/(2*x) = 0
0.25*2*x*(2*x+1)-x*x-1*2*x-1*2 = 0
0.5*x-2*x-2 = 0
-1.5*x-2 = 0
(-1.5*x-2)/(2*x) = 0
(-1.5*x-2)/(2*x) = 0 // * 2*x
-1.5*x-2 = 0
-1.5*x-2 = 0 // + 2
-1.5*x = 2 // : -1.5
x = 2/(-1.5)
