Solution for 14/(3+2x)=u equation: 


D( x )

2*x+3 = 0

2*x+3 = 0

2*x+3 = 0

2*x+3 = 0 // - 3

2*x = -3 // : 2

x = -3/2

x in (-oo:-3/2) U (-3/2:+oo)

14/(2*x+3) = u // - u

14/(2*x+3)-u = 0

14/(2*x+3)+(-u*(2*x+3))/(2*x+3) = 0

14-u*(2*x+3) = 0

14-2*u*x-3*u = 0

(14-2*u*x-3*u)/(2*x+3) = 0

(14-2*u*x-3*u)/(2*x+3) = 0 // * 2*x+3

14-2*u*x-3*u = 0

14-2*u*x-3*u = 0 // - 14-3*u

-2*u*x = -(14-3*u) // : -2*u

x = (-(14-3*u))/(-2*u)

x = (1/2)*u^-1*(14-3*u)

x = (1/2)*u^-1*(14-3*u)
