Want this question answered?
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.
i need a answer!!
solution..
An equation consists of two expressions joined by an '=' sign. If there is only one variable, you can usually solve the equation (find the value of the variable that makes the equation true). Example: 3x + 5 = 11: the solution is 2. (The techniques for finding the solution are a major part of algebra.) Check that 3(2) +5 = 6+5 = 11.
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.
