Solution for ((5a+7)/(a+2))-((3a-4)/(a+2)) equation: 


D( a )

a+2 = 0

a+2 = 0

a+2 = 0

a+2 = 0 // - 2

a = -2

a in (-oo:-2) U (-2:+oo)

(5*a+7)/(a+2)-((3*a-4)/(a+2)) = 0

(5*a+7)/(a+2)+(-1*(3*a-4))/(a+2) = 0

5*a-1*(3*a-4)+7 = 0

2*a+11 = 0

(2*a+11)/(a+2) = 0

(2*a+11)/(a+2) = 0 // * a+2

2*a+11 = 0

2*a+11 = 0 // - 11

2*a = -11 // : 2

a = -11/2

a = -11/2
