x in (-oo:+oo)
(9*x-2)/3 = (5*x-8)/13 // - (5*x-8)/13
(9*x-2)/3-((5*x-8)/13) = 0
(9*x-2)/3+(-1*(5*x-8))/13 = 0
(13*(9*x-2))/(3*13)+(-1*3*(5*x-8))/(3*13) = 0
13*(9*x-2)-1*3*(5*x-8) = 0
102*x-2 = 0
(102*x-2)/(3*13) = 0
(102*x-2)/(3*13) = 0 // * 3*13
102*x-2 = 0
102*x-2 = 0 // + 2
102*x = 2 // : 102
x = 2/102
x = 1/51
x = 1/51
