To solve a system of two equations, you can use one of three methods: substitution, elimination, or graphing. In the substitution method, you solve one equation for one variable and substitute that expression into the other equation. In the elimination method, you manipulate the equations to eliminate one variable by adding or subtracting them. Graphing involves plotting both equations on a graph and identifying their point of intersection, which represents the solution.
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
Two or more linear equations are commonly referred to as a "system of linear equations." This system can involve two or more variables and is used to find the values that satisfy all equations simultaneously. Solutions to such systems can be found using various methods, including graphing, substitution, and elimination. If a solution exists, it can be unique, infinitely many, or none at all, depending on the relationships between the equations.
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
Eliminate them from the equation. Note: This must be accomplished through the use of legitimate algebraic operations. Erasure is not permitted.

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.
