Tikz picture of two mathematical functions
I'm trying to draw the functions y=(0.05*0.4+0.1*2*x)/(0.05+0.1*2) and x=-0.1/(2*10*(y - 0.1))+y, by using tikz as follows
begin{tikzpicture}
begin{axis}[xmin=0,xmax=1,ymin=0,ymax=1, samples=1000, xlabel={$c$}, ylabel={$s$}]
addplot[blue, ultra thick] (x,(0.05*0.4+0.1*2*x)/(0.05+0.1*2));
addplot[red, ultra thick] (-0.1/(2*10*(x - 0.1))+x,x);
end{axis}
end{tikzpicture}
I obtained the picture:
But I'm not sure about the result (tikz seems to have drawn also the asymptote of second function). For me (and Mathematica) the result should be instead the following:
Can anybody tell me what's wrong with this picture and my tikz code?

Add appropriate curly brackets:addplot[blue, ultra thick] (x,{(0.05*0.4+0.1*2*x)/(0.05+0.1*2)}); addplot[red, ultra thick] ({-0.1/(2*10*(x - 0.1))+x},x);.

The TikZ/pgfplots parser gets confused about the brackets, it does not know which of them are delimiters of coordinates or expressions in the functions. So you have to help them a bit by adding curly brackets.
documentclass[tikz,border=3.14mm]{standalone}
usepackage{pgfplots}
pgfplotsset{compat=1.16}
begin{document}
begin{tikzpicture}
begin{axis}[xmin=0,xmax=1,ymin=0,ymax=1, samples=1000, xlabel={$c$},
ylabel={$s$},unbounded coords=discard]
addplot[blue, ultra thick] (x,{(0.05*0.4+0.1*2*x)/(0.05+0.1*2)});
addplot[red, ultra thick,domain=0:0.099] ({-0.1/(2*10*(x - 0.1))+x},x);
addplot[red, ultra thick,domain=0.11:1] ({-0.1/(2*10*(x - 0.1))+x},x);
end{axis}
end{tikzpicture}

@Mark Sure. (Sorry, was offline.) I removed the red asymptote. If you want to remove the blue one as well, removeaddplot[blue, ultra thick] (x,{(0.05*0.4+0.1*2*x)/(0.05+0.1*2)});. The red one was because you plotted over a singularity atx=0.1, and one easy way to remove it is to add two separate plots that avoid it.
