4*m-6 = 0
4*m-6 = 0
4*m-6 = 0
4*m-6 = 0 // + 6
4*m = 6 // : 4
m = 6/4
m = 3/2
m in (-oo:3/2) U (3/2:+oo)
1/2 = (3-(2*m))/(4*m-6) // - (3-(2*m))/(4*m-6)
1/2-((3-(2*m))/(4*m-6)) = 0
1/2-((3-2*m)/(4*m-6)) = 0
(-1*(3-2*m))/(4*m-6)+1/2 = 0
(-1*2*(3-2*m))/(2*(4*m-6))+(1*(4*m-6))/(2*(4*m-6)) = 0
1*(4*m-6)-1*2*(3-2*m) = 0
8*m-12 = 0
(8*m-12)/(2*(4*m-6)) = 0
(8*m-12)/(2*(4*m-6)) = 0 // * 2*(4*m-6)
8*m-12 = 0
8*m-12 = 0 // + 12
8*m = 12 // : 8
m = 12/8
m = 3/2
m in { 3/2}
m belongs to the empty set
