x in (-oo:+oo)
0 = 16-((x-(0.02*x))/0.81) // - 16-((x-(0.02*x))/0.81)
(x-(0.02*x))/0.81-16+0 = 0
(x-0.02*x)/0.81-16 = 0
(0.98*x)/0.81-16 = 0
(0.98*x)/0.81+(-16*0.81)/0.81 = 0
0.98*x-16*0.81 = 0
0.98*x-12.96 = 0
(0.98*x-12.96)/0.81 = 0
(0.98*x-12.96)/0.81 = 0 // * 0.81
0.98*x-12.96 = 0
0.98*x-12.96 = 0 // + 12.96
0.98*x = 12.96 // : 0.98
x = 12.96/0.98
x = 13.2244898
x = 13.2244898
