NCERT Solutions For Class 7 Maths Chapter 4 Simple Equations in Hindi - 2025-26
FAQs on NCERT Solutions For Class 7 Maths Chapter 4 Simple Equations in Hindi - 2025-26
1. How do Vedantu's NCERT Solutions for Class 7 Maths Chapter 4 help in scoring better marks?
Vedantu's NCERT Solutions for Class 7 Maths Chapter 4 are designed by subject matter experts to align perfectly with the CBSE 2025-26 syllabus. They provide a detailed, step-by-step methodology for solving every problem in the textbook. This helps students not only find the correct answer but also learn the proper format for presenting solutions in exams, which is crucial for scoring full marks.
2. What is the correct method for solving questions in Exercise 4.1 of Chapter 4, Simple Equations?
The primary focus of Exercise 4.1 is to check whether a given value is a solution to an equation. The correct method, as shown in the NCERT Solutions, involves substituting the given value of the variable into the Left Hand Side (LHS) of the equation. If the result equals the Right Hand Side (RHS), the value is a solution; otherwise, it is not. This process is clearly demonstrated for each problem.
3. How do the NCERT Solutions help in converting word problems from Exercise 4.4 into simple equations?
The NCERT Solutions for Exercise 4.4 excel at breaking down complex word problems. They guide students through a systematic process:
First, identify the unknown quantity in the problem and assign it a variable (e.g., 'x' or 'y').
Next, translate the phrases and conditions from the problem into mathematical expressions.
Finally, form a balanced equation by setting the relevant expressions equal to each other as per the problem's statement. This structured approach makes solving practical application questions much simpler.
4. Why is 'transposing' a term in an equation considered a valid step for solving it?
Transposing is a shortcut for the fundamental rule of balancing equations. When you transpose a term, you are essentially performing the same mathematical operation on both sides. For example, moving a '+7' from the LHS to the RHS as a '-7' is mathematically equivalent to subtracting 7 from both sides of the equation. This maintains the equality and simplifies the process of isolating the variable.
5. After solving an equation, how do you verify if the answer is correct as per the NCERT method?
The recommended method for verification is substitution. Once you have found the value of the variable, you should put this value back into the original equation. Calculate the value of the LHS and the RHS separately. If the value of the LHS is equal to the value of the RHS, your solution is confirmed to be correct. The NCERT Solutions demonstrate this verification step to encourage good practice.
6. What is the key difference between a mathematical 'expression' and a 'simple equation' in this chapter?
The key difference lies in the presence of an equality sign (=). An expression is a combination of variables and constants without an equality sign (e.g., 4x + 9). An equation, on the other hand, states that two expressions are equal (e.g., 4x + 9 = 21). Understanding this is crucial because only an equation can be 'solved' to find a specific value for the variable that makes the statement true.
7. When solving an equation like 3(n - 5) = -21, what is the first step recommended by the NCERT Solutions?
For an equation like 3(n - 5) = -21, the NCERT Solutions typically show two effective methods. However, a common first step is to simplify the equation by dividing both sides by the number outside the bracket, which is 3 in this case. This gives you (n - 5) = -7, which is a much simpler equation to solve by transposing the -5. This approach often reduces calculation errors compared to distributing the 3 first.
