[longye-tian]

Hi all @mmcky @HumphreyYang @SylviaZhaooo ,

I have translated the lecture linear_equations.md and put the translated version in the lecture folder.

Best,
Longye

@longye-tian this build is failing due to

/home/runner/work/lecture-intro.zh-cn/lecture-intro.zh-cn/lectures/linear_equations.md:806: WARNING: equation not found: la_se2

are you able to look this up to see what might be the issue?

[mmcky]

@longye-tian I gave this PR a go to see if some white space suggestions seem to fix the equation issue.

[mmcky]

Equations are definitely buggy in the translations.

The build is now reporting

/home/runner/work/lecture-intro.zh-cn/lecture-intro.zh-cn/lectures/linear_equations.md:858: WARNING: equation not found: la_se2
/home/runner/work/lecture-intro.zh-cn/lecture-intro.zh-cn/lectures/linear_equations.md:902: WARNING: equation not found: two_eq_demand_mat
/home/runner/work/lecture-intro.zh-cn/lecture-intro.zh-cn/lectures/linear_equations.md:902: WARNING: equation not found: two_eq_supply_mat

I wonder if its a mix of math directives and using $$ math syntax.

I will do some more tests tomorrow unless anyone else has good ideas.

Hi Matt @mmcky ,

Just add more empty lines.
Now I think it works.

Best,
Longye

@longye-tian these indentations shouldn't be needed. Do you add them for style?

[longye-tian]

I'll change it back. I think I put too much space after the : label:

[mmcky]

thanks @longye-tian -- it seems there needs to be white space around the :label: keys
