m in (-oo:+oo)
(1/4)*(m+3)+m/6 = (1/3)*(m+7) // - (1/3)*(m+7)
(1/4)*(m+3)-((1/3)*(m+7))+m/6 = 0
(1/4)*(m+3)+(-1/3)*(m+7)+m/6 = 0
1/4*(m+3)-1/3*(m+7)+m/6 = 0
(1/4*6*(m+3))/6+(-1/3*6*(m+7))/6+m/6 = 0
1/4*6*(m+3)-1/3*6*(m+7)+m = 0
m-1/2*m-19/2 = 0
1/2*m-19/2 = 0
(1/2*m-19/2)/6 = 0
(1/2*m-19/2)/6 = 0 // * 6
1/2*m-19/2 = 0
1/2*m-19/2 = 0 // + 19/2
1/2*m = 19/2 // : 1/2
m = 19/2/1/2
m = 19
m = 19
