(6*x-12)/6 = (16-(8*x))/4 // - (16-(8*x))/4
(6*x-12)/6-((16-(8*x))/4) = 0
(6*x-12)/6-((16-8*x)/4) = 0
(6*x-12)/6+(-1*(16-8*x))/4 = 0
(4*(6*x-12))/(4*6)+(-1*6*(16-8*x))/(4*6) = 0
4*(6*x-12)-1*6*(16-8*x) = 0
72*x-144 = 0
(72*x-144)/(4*6) = 0
(72*x-144)/(4*6) = 0 // * 4*6
72*x-144 = 0
72*x-144 = 0 // + 144
72*x = 144 // : 72
x = 144/72
