Lie Groups and Lie Algebras, chapter VIII, § 10. Maximal subalgebras of semi-simple Lie algebras

If $k$ is algebraically closed, every maximal solvable subalgebra of $\mathfrak{g}$ is a Borel subalgebra.

Bourbaki sets the proof directly after the statement, and the corpus does not separate them, so what is above is the statement and its proof together.
