Solution for 2/0.8=0.3/w equation: 


D( w )

w = 0

w = 0

w = 0

w in (-oo:0) U (0:+oo)

2/0.8 = 0.3/w // - 0.3/w

2/0.8-(0.3/w) = 0

2/0.8-0.3*w^-1 = 0

-0.3*w^-1 = -2.5 // : -0.3

w^-1 = 8.33333333

-1 < 0

1/(w^1) = 8.33333333 // * w^1

1 = 8.33333333*w^1 // : 8.33333333

0.12 = w^1

w = 0.12

w = 0.12
