Solution for 4/(w+4)=8/(2w+8)-3 equation: 


D( w )

2*w+8 = 0

w+4 = 0

2*w+8 = 0

2*w+8 = 0

2*w+8 = 0 // - 8

2*w = -8 // : 2

w = -8/2

w = -4

w+4 = 0

w+4 = 0

w+4 = 0 // - 4

w = -4

w in (-oo:-4) U (-4:+oo)

4/(w+4) = 8/(2*w+8)-3 // - 8/(2*w+8)-3

4/(w+4)-(8/(2*w+8))+3 = 0

4/(w+4)-8*(2*w+8)^-1+3 = 0

4/(w+4)-8/(2*w+8)+3 = 0

(4*(2*w+8))/((w+4)*(2*w+8))+(-8*(w+4))/((w+4)*(2*w+8))+(3*(w+4)*(2*w+8))/((w+4)*(2*w+8)) = 0

4*(2*w+8)-8*(w+4)+3*(w+4)*(2*w+8) = 0

6*w^2+48*w+96 = 0

6*w^2+48*w+96 = 0

6*(w^2+8*w+16) = 0

w^2+8*w+16 = 0

DELTA = 8^2-(1*4*16)

DELTA = 0

w = -8/(1*2)

w = -4 or w = -4

6*(w+4)^2 = 0

(6*(w+4)^2)/((w+4)*(2*w+8)) = 0

(6*(w+4)^2)/((w+4)*(2*w+8)) = 0 // * (w+4)*(2*w+8)

6*(w+4)^2 = 0

w+4 = 0 // - 4

w = -4

w in { -4} 

w belongs to the empty set
