x in (-oo:+oo)
(9-(2*x))/5 = (-13*x-8)/19 // - (-13*x-8)/19
(9-(2*x))/5-((-13*x-8)/19) = 0
(9-2*x)/5-((-13*x-8)/19) = 0
(9-2*x)/5+(-1*(-13*x-8))/19 = 0
(19*(9-2*x))/(5*19)+(-1*5*(-13*x-8))/(5*19) = 0
19*(9-2*x)-1*5*(-13*x-8) = 0
27*x+211 = 0
(27*x+211)/(5*19) = 0
(27*x+211)/(5*19) = 0 // * 5*19
27*x+211 = 0
27*x+211 = 0 // - 211
27*x = -211 // : 27
x = -211/27
x = -211/27
