It is not always the best method, sometimes elimination is the way you should solve systems. It is best to use substitution when you havea variable isolated on one side

What is the disadvantage of using the substitution method in solving linear equations rather than the graph method?
There are no disadvantages. There are three main ways to solve linear equations which are: substitution, graphing, and elimination. The method that is most appropriate can be found by looking at the equation.
Can quadratic systems be solved using elimination and substitution?
You can solve lineaar quadratic systems by either the elimination or the substitution methods. You can also solve them using the comparison method. Which method works best depends on which method the person solving them is comfortable with.
What is a method used to solve systems of equations in which the solution is the point where the lines intersect?
there are three methods: combination, substitution and decomposition.
Use the substitution method to solve the system of equations Enter your answer as an ordered pair?
Use the substitution method to solve the system of equations. Enter your answer as an ordered pair.y = 2x + 5 x = 1
Compare the symbolic method for solving linear equations to the methods of using a table or graph?
Equations = the method

What is graphing method?
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.
What is a method used to solve systems of equations in which the solution is the point where the lines intersect?
there are three methods: combination, substitution and decomposition.
How does the method for solving equations with fractional or decimal coefficients and constants compare with the method for solving equations with integer coefficients and constants?
The method is the same.
What is the advantage that the method od substitution has over the graphing method of solving system of equations?
Substitution is a way to solve without graphing, and sometimes there are equations that are impossible or very difficult to graph that are easier to just substitute. Mostly though, it is a way to solve if you have no calculator or cannot use one (for a test or worksheet).
How does a method for solving equations with fractions to decimal point that she's in conference compare with the method for solving equations with integer coefficients and constants?
The method is exactly the same.
Use the substitution method to solve the system of equations Enter your answer as an ordered pair?

How do you find the solution set of pair linear equations?
By the substitution method By the elimination method By plotting them on a graph
What is a method for solving a system of linear equations in which you multiply one or both equations by a number to get rid of a variable term?
It is called solving by elimination.
When solving systems of equations how do you determine what method to use?
if you are good at math, you would know. I'm not being mean, but sometimes it takes a little help from an adult.
