How to write the reaction for this titration process ( cant figure it out)

I started out with borax which i diluted 2x with in a 100ml volumetric flask.

I then titrated it with HCL, what would you guys do as a reaction for it?

The reaction will follow the equation:

2HCl + Na₂B₄O₇*10H₂O (borax) → 4H₃BO₃ + 2NaCl + 5H₂O
The resulting solution will be slightly acidic due to the boric acid formed so we can use an indicator which changes color at slightly acidic conditions to check for the end point.
