Solution for 7+30/a-5=6a/a-5 equation: 


D( a )

a = 0

a = 0

a = 0

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

30/a-5+7 = (6*a)/a-5 // - (6*a)/a-5

30/a-((6*a)/a)-5+5+7 = 0

30/a-6-5+5+7 = 0

30*a^-1 = -1 // : 30

a^-1 = -1/30

-1 < 0

1/(a^1) = -1/30 // * a^1

1 = -1/30*a^1 // : -1/30

-30 = a^1

a = -30

a = -30
