x in (-oo:+oo)
(3*x-3)/6+(8*x-1)/2 = -37 // + 37
(3*x-3)/6+(8*x-1)/2+37 = 0
(2*(3*x-3))/(2*6)+(6*(8*x-1))/(2*6)+(2*6*37)/(2*6) = 0
2*(3*x-3)+6*(8*x-1)+2*6*37 = 0
54*x-12+444 = 0
54*x+432 = 0
(54*x+432)/(2*6) = 0
(54*x+432)/(2*6) = 0 // * 2*6
54*x+432 = 0
54*x+432 = 0 // - 432
54*x = -432 // : 54
x = -432/54
