# Thread: Are these rules correct for simutaneous equations.

1. ## 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:

Okay.
Rule 3:

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?
