m in (-oo:+oo)
(m+1)/2-((m-1)/6) = m+3 // - m+3
(m+1)/2-((m-1)/6)-m-3 = 0
(m+1)/2+(-1*(m-1))/6-m-3 = 0
(6*(m+1))/(2*6)+(-1*2*(m-1))/(2*6)+(2*6*(-m))/(2*6)+(-3*2*6)/(2*6) = 0
6*(m+1)-1*2*(m-1)+2*6*(-m)-3*2*6 = 0
4*m-12*m-36+8 = 0
8-8*m-36 = 0
-8*m-28 = 0
(-8*m-28)/(2*6) = 0
(-8*m-28)/(2*6) = 0 // * 2*6
-8*m-28 = 0
-8*m-28 = 0 // + 28
-8*m = 28 // : -8
m = 28/(-8)
m = -7/2
m = -7/2
