D( x )

x = 0

5*x = 0

x = 0

x = 0

5*x = 0

5*x = 0

5*x = 0 // : 5

x = 0

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

3/x+2 = 4/(5*x)+21/10 // - 4/(5*x)+21/10

3/x-(4/(5*x))-(21/10)+2 = 0

3/x+(-4/5)*x^-1-21/10+2 = 0

11/5*x^-1 = 1/10 // : 11/5

x^-1 = 1/22

-1 < 0

1/(x^1) = 1/22 // * x^1

1 = 1/22*x^1 // : 1/22

22 = x^1

x = 22

x = 22
