A single equation is several unknowns will rarely have a unique solution. A system of n equations in n unknown variables may have a unique solution.

0You can use a graph to solve systems of equations by plotting the two equations to see where they intersect

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.

It is important to know several techniques for solving equations and inequalities because one may work better than another in a particular situation.

By elimination or substitution

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.

Equations allow you to solve mathematical problems.

It depends on the equations.

The answer depends on whether they are linear, non-linear, differential or other types of equations.

A "system" of equations is a set or collection of equations that you deal with all together at once. Linear equations (ones that graph as straight lines) are simpler than non-linear equations, and the simplest linear system is one with two equations and two variables.

A way to solve a system of equations by keeping track of the solutions of other systems of equations. See link for a more in depth answer.

Any solution to a system of linear equations must satisfy all te equations in that system. Otherwise it is a solution to AN equation but not to the system of equations.
