FAQs on Concise Mathematics Class 6 ICSE Solutions for Chapter 20 - Substitution (Including Use of Brackets as Grouping Symbols)
1. Where can I find these solutions for Class 6 Mathematics chapter 20?
You can find all the solutions for the problems that are given in the exercises on the Vedantu site and app. These solutions are written by professional teachers in that particular field. Along with these solutions, students can also find important formulas to clear their doubts on their own. These solutions are provided free of cost and there are no additional charges. Once students sign in and then they will be able to find solutions in a pdf format. Every student should take advantage of these free resources that will surely help them crack their exams.
2. What are the steps involved in the chapter 20 for ICSE Mathematics class 6 that explains “The substitution method”?
The major steps involved in the substitution method are briefly explained here at Vedantu. Substitution means replacement that helps us to find the solution for the problem. The first step is to solve one of the equations either for the variable x or y that is given in the problem. The second step is to substitute the solution from step 1 to the other equation. The last step is to solve the equation to find the value of the other variable.
3. According to the solutions for ICSE Class 6 Maths, can we use this substitution method to solve the system of equations in three variables(x, y, and z variables)?
Whenever we solve the system of equations with three variables(x, y, and z), we use the substitution method. Sometimes we use the elimination method to make the single system into the system of two equations with two variables(x and y). There are some other methods to solve linear equations in two variables. Students who want to know those methods are suggested to download the pdf of ICSE Board Class 10 Mathematics chapter 20 Substitution solutions from vedantu website.
4. What is the main advantage of having solutions for Class 6 Mathematics chapter 20?
There are many advantages to having the solution of chapter 20 Mathematics. At the end of each exercise, students will learn how to solve a sum in an easy way as well as formulae. Another advantage of using the substitution method is that it gives the accurate values for the variables (x and y), that correspond to the point of intersection. With the help of these solutions, students can improve their problem-solving ability and improve their confidence towards the subject. This will get students familiar with the paper pattern, question type. With the help of this pdf, students will be able to understand the formulae in a simple way.
5. What are the different methods explained in the pdf of ICSE Board Class 10 Mathematics chapter 20 Substitution solutions?
The substitution method is one of the common algebraic methods to solve simultaneous linear equations. It explains how to substitute the value of any one of the variables from one equation to another equation. Apart from the substitution method, there are other two algebraic methods of solving linear equations. They are the elimination method and the cross multiplication method. We can also solve a system of linear equations graphically. 'Vedantu' provides free study materials which can be downloaded from the Vedantu site and app.
