Solution for 6+20/a-4=5a/a-4 equation: 


D( a )

a = 0

a = 0

a = 0

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

20/a-4+6 = (5*a)/a-4 // - (5*a)/a-4

20/a-((5*a)/a)-4+4+6 = 0

20/a-5-4+4+6 = 0

20*a^-1 = -1 // : 20

a^-1 = -1/20

-1 < 0

1/(a^1) = -1/20 // * a^1

1 = -1/20*a^1 // : -1/20

-20 = a^1

a = -20

a = -20
