Solution for 12/r=4/(0.5r-1) equation: 


D( r )

r = 0

0.5*r-1 = 0

r = 0

r = 0

0.5*r-1 = 0

0.5*r-1 = 0

0.5*r-1 = 0 // + 1

0.5*r = 1 // : 0.5

r = 1/0.5

r = 2

r in (-oo:0) U (0:2) U (2:+oo)

12/r = 4/(0.5*r-1) // - 4/(0.5*r-1)

12/r-(4/(0.5*r-1)) = 0

12/r-4*(0.5*r-1)^-1 = 0

12/r-4/(0.5*r-1) = 0

(-4*r)/(r*(0.5*r-1))+(12*(0.5*r-1))/(r*(0.5*r-1)) = 0

12*(0.5*r-1)-4*r = 0

2*r-12 = 0

(2*r-12)/(r*(0.5*r-1)) = 0

(2*r-12)/(r*(0.5*r-1)) = 0 // * r*(0.5*r-1)

2*r-12 = 0

2*r-12 = 0 // + 12

2*r = 12 // : 2

r = 12/2

r = 6

r = 6
