It is using a set of two equations, adding them together, eliminating one variable and finding the value of the other variable.
The difference depends on what m and n equal. If they are both variable then it dpends on what the equations are for each variable.

To solve a linear equation, you can use algebraic techniques such as isolating the variable by performing inverse operations. For example, if you have an equation like 2x + 3 = 9, you can subtract 3 from both sides to isolate the variable x. To graph a linear equation, you can plot points by choosing values for one variable, finding the corresponding values for the other variable, and connecting the points to form a straight line. The slope-intercept form (y = mx + b) is particularly useful for graphing linear equations, where m represents the slope and b represents the y-intercept.
No, tables are not ALWAYS the best way to find a value. They may be the easiest way or not.
It is about finding a value of the variable (or variables) that make the equation a true statement.

They can be, but not always. Other methods (equations, graphs) may be the best way.

The variables stand for an unknown number that has not yet been identified which has been kept as a variable for the purpose of finding the value of.
It very much depends on the equation. The procedure for solving an equation with just one variable is so very different from the procedure for finding solutions to non-linear equations in several variables.
In algebraic expressions, the keyword "1x-9" represents a linear equation with one variable (x) and a constant term (-9). This expression is significant because it helps to simplify and solve equations by isolating the variable and finding its value.
