3*x-13 = 0
3*x-13 = 0
3*x-13 = 0
3*x-13 = 0 // + 13
3*x = 13 // : 3
x = 13/3
x in (-oo:13/3) U (13/3:+oo)
3/4 = (2*x-8)/(3*x-13) // - (2*x-8)/(3*x-13)
3/4-((2*x-8)/(3*x-13)) = 0
(-1*(2*x-8))/(3*x-13)+3/4 = 0
(-1*4*(2*x-8))/(4*(3*x-13))+(3*(3*x-13))/(4*(3*x-13)) = 0
3*(3*x-13)-1*4*(2*x-8) = 0
x-7 = 0
(x-7)/(4*(3*x-13)) = 0
(x-7)/(4*(3*x-13)) = 0 // * 4*(3*x-13)
x-7 = 0
x-7 = 0 // + 7
x = 7
x = 7
