Using Latex systeme package with subscripted variables as well as parameters

Question

I am trying to use the CTAN systeme package with

\systeme{ x_0 + 2x_1 + 4x_2 = 1,x_1 - 9x_2 = -2,( 9 k - 36 ) x_2 = h + 2 k - 10}

As written, it does not properly recognize the variables x_0, x_1, x_2 due to the presence of the parameter k \systeme[x]{...} does not work in this case.

How do I specify the variables?

You need to tell \systeme what are the unknowns and to mask the minus sign in the coefficient.

\documentclass{article}
\usepackage{systeme}
\begin{document}
\systeme[x_0x_1x_2]{
  x_0 + 2x_1 + 4x_2 = 1,
  x_1 - 9x_2 = -2,
  ( 9 k - 36 ) x_2 = h + 2 k - 10
}
\end{document}
