How do you solve Linear Equations with the substitution method?

∙ 12y ago
You just plug in the value of the given variable. For example:
y=3+2
2y=x (now you substitute y for 3+2)
2(3+2)=x (now solve the equation using distributive property)
6+4=x
10=x
Tuhduh!! All done using the substitution property.

What are two symbolic techniques used to solve linear equations?
Elimination and substitution are two methods.
Use the substitution method to solve the system of equations Choose the correct ordered pair?
2x+7y=29 x=37-8y
To solve a three variable system of equations you can use a combination of the elimination and substitution methods?
True. To solve a three variable system of equations you can use a combination of the elimination and substitution methods.
How do you solve linear equations with bracets?
You simplify the brackets first and then you will have linear equations without brackets!
How do you do linear equations?
To solve linear equations, you always use the inverse operations
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 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.
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
How can you solve a linear equation?
by elimination,substitution or through the matrix method.
What are two symbolic techniques used to solve linear equations?
Elimination and substitution are two methods.
Solve linear equations with complex coefficients on both sides?
You would solve them in exactly the same way as you would solve linear equations with real coefficients. Whether you use substitution or elimination for pairs of equations, or matrix algebra for systems of equations depends on your requirements. But the methods remain the same.
What are two symbolic techniques used to solve linear equations and which do you feel is better?
Elimination and substitution are two methods.
When using the substitution method to solve a nonlinear system of equations you should first see if you can one variable in one of the equations in the system?
isolate
What are the ways to solve a system of linear equations in two variables?
the substitution method in which you take each variable and you find out the value and then plug it into the original equation.the adding and subtracting method in which you subtract\add equations to take out a variable and you can figure out what the other variable is. then you also substitute that into that into the original variable

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).
What are two symbolic techniques used to solve a system of linear equations in two variables?
I have never seen the term 'symbolic' used in this way. There are 4 methods used to solve a system of linear equations in two variables. Graphing, Substitution, Elimination, and Cramer's Rule.
