It depends on the equations.
i need to do this for math class
because you need maths in your life.. everyone does
In systems of equations, the graphing method is solving x and y by graphing out the two equations. x and y being the coordinates of the two line's intersection.
The Cauchy kovalevskaya theorem tells us about solutions to systems of differential equations. If we look at m equations in n dimension, with coefficient that are analytic function, we can know about the existence of solutions using this theorem.
You can use a graph to solve systems of equations by plotting the two equations to see where they intersect
It is important to know several techniques for solving equations and inequalities because one may work better than another in a particular situation.
The answer will depend on what kinds of equations: there are linear equations, polynomials of various orders, algebraic equations, trigonometric equations, exponential ones and logarithmic ones. There are single equations, systems of linear equations, systems of linear and non-linear equations. There are also differential equations which are classified by order and by degree. There are also partial differential equations.
Systems of equations don't equal numbers.

If they are quadratic equations then if their discriminant is less than zero then they have no solutions
Systems of equations can have just about any number of solutions: zero, one, two, etc., or even infinitely many solutions.
They are called equivalent systems.
If done properly there are no disadvantages.
