x in (-oo:+oo)
(3*x-12)/5+(x+19)/7 = 7 // - 7
(3*x-12)/5+(x+19)/7-7 = 0
(7*(3*x-12))/(5*7)+(5*(x+19))/(5*7)+(-7*5*7)/(5*7) = 0
7*(3*x-12)+5*(x+19)-7*5*7 = 0
26*x-245+11 = 0
26*x-234 = 0
(26*x-234)/(5*7) = 0
(26*x-234)/(5*7) = 0 // * 5*7
26*x-234 = 0
26*x-234 = 0 // + 234
26*x = 234 // : 26
x = 234/26
x = 9
x = 9
