m in (-oo:+oo)
(12*m+5)/6 = (9-(13*m))/5 // - (9-(13*m))/5
(12*m+5)/6-((9-(13*m))/5) = 0
(12*m+5)/6-((9-13*m)/5) = 0
(12*m+5)/6+(-1*(9-13*m))/5 = 0
(5*(12*m+5))/(5*6)+(-1*6*(9-13*m))/(5*6) = 0
5*(12*m+5)-1*6*(9-13*m) = 0
138*m-29 = 0
(138*m-29)/(5*6) = 0
(138*m-29)/(5*6) = 0 // * 5*6
138*m-29 = 0
138*m-29 = 0 // + 29
138*m = 29 // : 138
m = 29/138
m = 29/138
