How does writing equivalent equations help you solve a system of equations?

You can write an equivalent equation from a selected equation in the system of equations to isolate a variable. You can then take that variable and substitute it into the other equations. Then you will have a system of equations with one less equation and one less variable and it will be simpler to solve.

Solve the following system of equations using sustitution x6y-4 x-2y 28?
To solve a system of equations, you need equations (number phrases with equal signs).
How can you solve a system of equations?
The answer depends on whether they are linear, non-linear, differential or other types of equations.
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
You can solve a system of equations by translating it into a matrix manipulating the matrix until it has eliminated terms and then translating it back to equations?
True
If you are asked to solve a system of equations in which there is no linear equation to start with you can sometimes begin isolating and substituting a variable that is squared in both equations?
true
How can you solve problems involving equivalent expressions?
In the same way that you would solve equations because equivalent expressions are in effect equations

Translate this word problem as a system of equations and then solve using substitution?
A system of equations is two or more equations that share at least one variable. Once you have determined your equations, solve for one of the variables and substitute in that solution to the other equation.
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.
Is there one method to solve a system of equations?
No, there are several methods.
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 could you show that two equations aren't equivalent?
One way would be to solve the two equations. If they have exactly the same solution set, they are equivalent. Otherwise they are not.
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
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
