(5*x)/2-9 = (2*x-7)/6 // - (2*x-7)/6
(5*x)/2-((2*x-7)/6)-9 = 0
(-1*(2*x-7))/6+(5*x)/2-9 = 0
(-1*2*(2*x-7))/(2*6)+(5*6*x)/(2*6)+(-9*2*6)/(2*6) = 0
5*6*x-1*2*(2*x-7)-9*2*6 = 0
26*x-108+14 = 0
26*x-94 = 0
(26*x-94)/(2*6) = 0
(26*x-94)/(2*6) = 0 // * 2*6
26*x-94 = 0
26*x-94 = 0 // + 94
26*x = 94 // : 26
x = 94/26
x = 47/13
x = 47/13
