(5*x)/16-(1/5) = 1-((4/5)*(x-(1/20))) // - 1-((4/5)*(x-(1/20)))
(4/5)*(x-(1/20))+(5*x)/16-(1/5)-1 = 0
(4/5)*(x-1/20)+(5*x)/16-1/5-1 = 0
4/5*(x-1/20)+(5*x)/16-1/5-1 = 0
(4/5*5*16*(x-1/20))/(5*16)+(5*5*x)/(5*16)+(-1*16)/(5*16)+(-1*5*16)/(5*16) = 0
4/5*5*16*(x-1/20)+5*5*x-1*16-1*5*16 = 0
89*x-80-16-16/5 = 0
89*x-80-96/5 = 0
89*x-496/5 = 0
(89*x-496/5)/(5*16) = 0
(89*x-496/5)/(5*16) = 0 // * 5*16
89*x-496/5 = 0
89*x-496/5 = 0 // + 496/5
89*x = 496/5 // : 89
x = 496/5/89
x = 496/445
x = 496/445
