    Are these rules correct for simutaneous equations.

    Rule 1:
    If the solution of two equations is like 2=7, then the equations are not equilateral with no common solution.

    Rule 2:
    If the solution of two equations is like 0=0, then the equations are equilateral with infinite common solution.

    Rule 3:

    If the solution of two equations is like 2=2 or 7=7 or 9=9, then the equations have only one solution.

    "equilateral"? Okay.
    Rule 2:
    If the solution of two equations is like 0=0, then the equations are equilateral with infinite common solution.
    Okay.
    Rule 3:
    If the solution of two equations is like 2=2 or 7=7 or 9=9, then the equations have only one solution.
    Why is this case different from 0=0? I assume you mean x = 2 or y = 7.

    Rule #4:
    Don't memorize so many rules that you forget to think about what you are doing?
