About NCERT Solutions for Class 7 Maths Chapter 4

In 7 Maths Chapter 4 Simple Equations, we will study about the formation of linear equations in one variable (A variable takes on different numerical values; its value is not fixed. Variables are denoted usually by letters of the alphabets, such as x, y, z, l, m, n, p, etc.). In an equation there is always an equality sign. The equality sign shows that the value of expression to the left hand side or LHS is equal to the value of the expression to the right hand side or RHS. Remember the following things for an equation:
1. If we subtract the same number from both sides of an equality, it still holds.
2. If we multiply or divide both sides of the equality by the same non-zero number, it still holds.
3. Transposing a number (changing the side of the number) is the same as adding or subtracting the number from both sides.
Note: If we fail to do the same mathematical operation on both sides of an equality, the equality does not hold.
To solve the practical problems based on equations, first convert the situation into equation and then apply the mathematical operation on it.

Important Questions on Class 7 Maths Chapter 4

Check whether the value given in the brackets is a solution to the given equation or not: n + 5 = 19 [ n = 1].
n + 5 = 19
Putting n = 1 in L.H.S., 1 + 5 = 6
L.H.S. R.H.S.,
n = 1 is not the solution of given equation.
अध्यापिका बताती है कि उनकी कक्षा में एक विद्यार्थी द्वारा प्राप्त किए गए अधिकतम अंक, प्राप्त किए न्यूनतम अंक का दुगुना जमा 7 है। प्राप्त किए गए अधिकतम अंक 87 हैं। प्राप्त किए गए न्यूनतम अंक क्या हैं?
माना, न्यूनतम अंक = y
प्रश्न के अनुसार,
2 y + 7 = 87
So, 2y = 87 – 7 = 80
and y = 80/2 = 40

अतः, प्राप्त किए गए न्यूनतम अंक 40 हैं।

Write equations for the following statement: The sum of numbers x and 4 is 9.
x + 4 = 9
Write the following equations in statement form: 4 p – 2 = 18.
If you take away 2 from 4 times p you get 18.
इरफ़ान कहता है कि उसके पास परमीत के पास जितने कंचे हैं उनके पाँच गुने से 7 अधिक कंचे हैं। इरफ़ान के पास 37 कंचे हैं। परमीत के पास कितने कंचे हैं?
माना, परमीत के पास कंचों की कुल संख्या = m
प्रश्न के अनुसार,
5 m + 7 = 37
So, 5m = 37 – 7 = 30
and m = 30/5 = 6
अतः, परमीत के पास कुल 6 कंचे हैं।
लक्ष्मी के पिता की आयु 49 वर्ष है। उनकी आयु लक्ष्मी की आयु के तीन गुने से 4 वर्ष अधिक है। लक्ष्मी की आयु क्या है?
माना, लक्ष्मी की आयु = y वर्ष
इसलिए, पिता की आयु = 3 y + 4 वर्ष
प्रश्न के अनुसार,
3 y + 4 = 49
So, 3y = 49 – 4 = 45
and y = 45/3 = 15
अतः, लक्ष्मी की आयु 15 वर्ष है।
