D( x )
3*x = 0
3*x = 0
3*x = 0
3*x = 0 // : 3
x = 0
x in (-oo:0) U (0:+oo)
v/(3*x) = w/y // - w/y
v/(3*x)-(w/y) = 0
1/3*v*x^-1 = w*y^-1 // : 1/3*v
x^-1 = 3*v^-1*w*y^-1
-1 < 0
1/(x^1) = 3*v^-1*w*y^-1 // * x^1
1 = 3*v^-1*w*x^1*y^-1 // : 3*v^-1*w*y^-1
1/(3*v^-1*w*y^-1) = x^1
x = 1/(3*v^-1*w*y^-1)
x = 1/(3*v^-1*w*y^-1)
