What is Substuition method in maths??
Explain clearly
Answers
Step-by-step explanation:
The substitution method is the algebraic method to solve simultaneous linear equations. As the word says, in this method, the value of one variable from one equation is substituted in the other equation.In this way, a pair of the linear equation gets transformed into one linear equation with only one variable, which can then easily be solved. Before moving to solve the linear equations using the substitution method, get an idea on what the algebraic method and graphical method is.
Algebraic Method
An Algebraic method is a collection of several methods, which are used to solve a pair of the linear equations that includes two variables. Generally, the algebraic method can be sub-divided into three categories:
- Substitution method
- Elimination method
- Cross-multiplication method
Graphical Method
The graphical method is also known as the geometric method and is used to solve the system of linear equations. In this method, the equations are designed based on the objective function and constraints. To solve the system of linear equations, this method has undergone different steps to obtain the solutions.
In this article, we will focus mainly on solving the linear equations using the first algebraic method called “Substitution method
Answer:
Substuition method
In the substitution method you solve for one variable, and then substitute that expression into the other equation. The important thing here is that you are always substituting values that are equivalent. For
Example:
Roni is 5 years older than four times his daughter's age.
