You cannot solve one linear equation in two unknown variables (x and y), although some non-linear equations will suffice. You need two independent linear equations. All you can do is express one of the variables in terms of the other, but that is not solving the equation.
Eliminate them from the equation. Note: This must be accomplished through the use of legitimate algebraic operations. Erasure is not permitted.
Not sure that you can slove anything. -2w = r + s is one linear equation in 3 unknown variables. You need three independent equations in 3 variables to be able to solve them.
By elimination or substitution
They are called equivalent systems.
You can use a graph to solve systems of equations by plotting the two equations to see where they intersect
Systems of equations can have just about any number of solutions: zero, one, two, etc., or even infinitely many solutions.

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.

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.
If you mean: 4n-2n = 4 then 2n = 4 and n = 2

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.
