4*w+6 = 0
4*w+6 = 0
4*w+6 = 0
4*w+6 = 0 // - 6
4*w = -6 // : 4
w = -6/4
w = -3/2
w in (-oo:-3/2) U (-3/2:+oo)
(w+14)/(4*w+6) = 3/4 // - 3/4
(w+14)/(4*w+6)-(3/4) = 0
(w+14)/(4*w+6)-3/4 = 0
(4*(w+14))/(4*(4*w+6))+(-3*(4*w+6))/(4*(4*w+6)) = 0
4*(w+14)-3*(4*w+6) = 0
38-8*w = 0
(38-8*w)/(4*(4*w+6)) = 0
(38-8*w)/(4*(4*w+6)) = 0 // * 4*(4*w+6)
38-8*w = 0
38-8*w = 0 // - 38
-8*w = -38 // : -8
w = -38/(-8)
w = 19/4
w = 19/4
