n in (-oo:+oo)
(5*n+1)/2-((3*n-10)/3) = (6-(2*n))/4 // - (6-(2*n))/4
(5*n+1)/2-((3*n-10)/3)-((6-(2*n))/4) = 0
(5*n+1)/2-((3*n-10)/3)-((6-2*n)/4) = 0
(5*n+1)/2+(-1*(3*n-10))/3+(-1*(6-2*n))/4 = 0
(3*4*(5*n+1))/(2*3*4)+(-1*2*4*(3*n-10))/(2*3*4)+(-1*2*3*(6-2*n))/(2*3*4) = 0
3*4*(5*n+1)-1*2*4*(3*n-10)-1*2*3*(6-2*n) = 0
36*n+12*n-36+92 = 0
48*n+56 = 0
(48*n+56)/(2*3*4) = 0
(48*n+56)/(2*3*4) = 0 // * 2*3*4
48*n+56 = 0
48*n+56 = 0 // - 56
48*n = -56 // : 48
n = -56/48
n = -7/6
