x in (-oo:+oo)
70 = (2.37*(x+1))/0.1223+x // - (2.37*(x+1))/0.1223+x
70-((2.37*(x+1))/0.1223)-x = 0
70-19.37857727*(x+1)-x = 0
70-19.37857727*(x+1)-x = 0
70-20.37857727*x-19.37857727 = 0
50.62142273-20.37857727*x = 0
50.62142273-20.37857727*x = 0
50.62142273-20.37857727*x = 0 // - 50.62142273
-20.37857727*x = -50.62142273 // : -20.37857727
x = -50.62142273/(-20.37857727)
x = 2.48405088
x = 2.48405088
