When you have a system of equations and you can solve for one in terms of th others and then replace it in the other equations that is substitution.
x+y=15
x-y=1
well the second one can be x=1+y
x+y=15 then can be (1+y)+y=15 by substitution.
1+2y=15
2y=14
y=7
Then x+7=15
x=8
The substitution method undoes the chain rule.
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 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.
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.
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

Yes
That's exactly the purpose of the substitution method ... to get an equation with one less variable. When you have it, you solve it for the variable that's left.

By the substitution method By the elimination method By plotting them on a graph
by elimination,substitution or through the matrix method.

There is not Substitution Property of Congruence. There is, however, one for Equality, called the Substitution Property of Equality.
Both the substitution method and the linear combinations method (or elimination method) are techniques used to solve systems of linear equations. In the substitution method, one equation is solved for one variable, which is then substituted into the other equation. In contrast, the linear combinations method involves adding or subtracting equations to eliminate one variable, allowing for the direct solution of the remaining variable. While both methods aim to find the same solution, they differ in their approach to manipulating the equations.
well,both are different methods but the answers are same.
