x in (-oo:+oo)
X/265 = (x-280)/185 // - (x-280)/185
X/265-((x-280)/185) = 0
(-1*(x-280))/185+X/265 = 0
(-1*265*(x-280))/(185*265)+(185*X)/(185*265) = 0
185*X-1*265*(x-280) = 0
185*X-265*x+74200 = 0
(185*X-265*x+74200)/(185*265) = 0
(185*X-265*x+74200)/(185*265) = 0 // * 185*265
185*X-265*x+74200 = 0
185*X-265*x+74200 = 0 // - 185*X+74200
-265*x = -(185*X+74200) // : -265
x = (-(185*X+74200))/(-265)
x = (185*X+74200)/265
x = (185*X+74200)/265
