x in (-oo:+oo)
1.2 = (x-y)/190000 // - (x-y)/190000
1.2-((x-y)/190000) = 0
(-1*(x-y))/190000+1.2 = 0
(-1*(x-y))/190000+(1.2*190000)/190000 = 0
1.2*190000-1*(x-y) = 0
y-x+228000 = 0
(y-x+228000)/190000 = 0
(y-x+228000)/190000 = 0 // * 190000
y-x+228000 = 0
y-x+228000 = 0 // - y+228000
-x = -(y+228000) // * -1
x = y+228000
x = y+228000
