~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

May be other tutors will offer you better advise and/or solution.

My advise is: read these lessons in this site:

    - Solution of the linear system of two equations in two unknowns using determinant,
    - Solution of the linear system of two equations in two unknowns by the Substitution method,
    - Solution of the linear system of two equations in two unknowns by the Elimination method

    - Solving systems of linear equations in 3 unknowns by the Substitution method,
    - BRIEFLY on solving systems of linear equations in 3 unknowns by the Substitution method

    - Solving systems of linear equations in 3 unknowns by the Elimination method
    - BRIEFLY on solving systems of linear equations in 3 unknowns by the Elimination method

    - HOW TO solve system of linear equations in three unknowns using determinant (Cramer's rule)

The best thing is to know all these methods.
(Actually, it is the necessary and sufficient condition.)

It is also a prerequisite for discussing which method is better.

And when you really know all of them, this question "which method is better?" will not even arise at all.
At least, at the level of school Math with 2x2 and 3x3 systems of linear equations.

Why don't YOU state which ones(s) you prefer? Isn't that what this assignment is all about? I prefer elimination,

followed by substitution. Again, this is not about what I think or prefer, but about your thoughts and preference.
