Solution for 8/(m+3)=4/m equation: 


D( m )

m = 0

m+3 = 0

m = 0

m = 0

m+3 = 0

m+3 = 0

m+3 = 0 // - 3

m = -3

m in (-oo:-3) U (-3:0) U (0:+oo)

8/(m+3) = 4/m // - 4/m

8/(m+3)-(4/m) = 0

8/(m+3)-4*m^-1 = 0

8/(m+3)-4/m = 0

(8*m)/(m*(m+3))+(-4*(m+3))/(m*(m+3)) = 0

8*m-4*(m+3) = 0

4*m-12 = 0

(4*m-12)/(m*(m+3)) = 0

(4*m-12)/(m*(m+3)) = 0 // * m*(m+3)

4*m-12 = 0

4*m-12 = 0 // + 12

4*m = 12 // : 4

m = 12/4

m = 3

m = 3
