Solution for 2/n=14/(n+30) equation: 


D( n )

n+30 = 0

n = 0

n+30 = 0

n+30 = 0

n+30 = 0 // - 30

n = -30

n = 0

n = 0

n in (-oo:-30) U (-30:0) U (0:+oo)

2/n = 14/(n+30) // - 14/(n+30)

2/n-(14/(n+30)) = 0

2/n-14*(n+30)^-1 = 0

2/n-14/(n+30) = 0

(-14*n)/(n*(n+30))+(2*(n+30))/(n*(n+30)) = 0

2*(n+30)-14*n = 0

60-12*n = 0

(60-12*n)/(n*(n+30)) = 0

(60-12*n)/(n*(n+30)) = 0 // * n*(n+30)

60-12*n = 0

60-12*n = 0 // - 60

-12*n = -60 // : -12

n = -60/(-12)

n = 5

n = 5
