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.
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.
How do you solve systems of equations by using elimination?
Multiply every term in both equations by any number that is not 0 or 1, and has not been posted in our discussion already. Then solve the new system you have created using elimination or substitution method:6x + 9y = -310x - 6y = 58
Why is substitution the best method in solving systems of equations?
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 elimination method in algebra?
a method
The elimination method works when the equations are in?
standard
State two methods of solving simultaneous equations?
The elimination method and the substitutionmethod.
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

How do you decide whether to use elimination or subsitution to solve a three-variable system?
There is no simple answer. Sometimes, the nature of one of the equations lends itself to the substitution method but at other times, elimination is better. If they are non-linear equations, and there is an easy substitution then that is the best approach. With linear equations, using the inverse matrix is the fastest method.

How do you solve this problem -3x plus 2y equals 1 in elimination?
The elimination method only works with simultaneous equations, hence another equation is needed here for it to be solvable.
How do you solve 3 dimensional equations?
You can solve the system of equations with three variables using the substitute method, or using matrix operations.
True or false The key to using the elimination method is to find variable terms in the two equations that have equal or opposite coefficients?
True
The elimination method works when the equations are in form and the coefficients of one of the variables are equal or opposite?

Solve the system of equations using the elimination method negative x plus y equals negative 3 and 3x plus 2y equals 9?
By elimination: x = 3 and y = 0
