When talking about a "system of equations", you would normally expect to have two or more equations. It is quite common to have as many equations as you have variables, so in this case you should have two equations.
Yes, addition or subtraction can be used to solve a system of equations, particularly in the method known as elimination. By adding or subtracting equations, you can eliminate one of the variables, making it easier to solve for the other variable. This method is effective when the coefficients of one variable are opposites or can be made to be opposites through multiplication. However, it is not the only method; substitution and graphing are also common approaches.
There is only one equation, so it's not a system of equations.
By elimination: x = 3 and y = 0
When solving simultaneous equations, you can use either addition or subtraction, depending on the equations. If the coefficients of one variable are the same (or negatives of each other), you can add or subtract the equations to eliminate that variable. This method simplifies the system, allowing you to solve for the remaining variable. The choice to add or subtract should be based on which method will simplify your calculations most effectively.

Simultaneous equations can be solved using the elimination method.

Systems of equations don't equal numbers.
There is only one equation, so it's not a system of equations.
By elimination: x = 3 and y = 0
It probably means that one of the equations is a linear combination of the others/ To that extent, the system of equations is over-specified.
the system of equations 3x-6y=20 and 2x-4y =3 is?Well its inconsistent.
