Q.1. Find the value of y for the equation: 2y+52=372

8

Solution: Given, 2y+52=372

⇒2y=372-52 (Transposing 52 to R.H.S.)

⇒2y=37-52

⇒2y=322 ⇒2y=16

On dividing both sides by 2, we get,

⇒y=162=8

Hence, the required answer is 8.

Q.2. Find the value of 10t for the equation 5t+28=10

-36

Solution: Given, 5t+28=10

⇒5t=10-28 (Transposing 28 to R.H.S.)

⇒5t=-18

On dividing both sides by 5, we get,

⇒t=-185

∴10t=-185×10=-36 Hence, the required answer is -36.

Q.3. What is the value of a in the equation a5+3=2.

-5

Solution: Given, a5+3=2

Transposing 3 to R.H.S., we get,

⇒a5=2-3 ⇒a5=-1

On multiplying both sides by 5, we get,

⇒a5×5=-1×5

⇒a=-5 Hence, the required answer is -5.

Q.4. Solve the equation and find the value of q: q4+7=5

-8

Solution: Given, q4+7=5

⇒q4=5-7 (Transposing 7 to R.H.S.)

⇒q4=-2

On multiplying both sides by 4, we get,

⇒q4×4=-2×4

⇒q=-8 Hence, the required answer is -8.

Q.5. Solve the following equation: 52x=-5.

-2

Solution: Given, 52x=-5

On multiplying both sides by 2, we get,

⇒5×2×2=-5×2 ⇒5x=-10

On dividing both sides by 5, we get,

⇒5×5=-105

⇒x=-2 Hence, the required answer is -2.

Q.6. Find the value of 2x for the equation 52x=254.

5

Solution: Given, 52x=254

On multiplying both sides by 2, we get,

⇒5×2×2=254×2 ⇒5x=252

On dividing both sides by 5, we get,

⇒5×5=252×15

⇒x=52 Therefore, the value of x is 52. Hence, the value of 2x is 52×2=5.

Q.7. Find the value of m in the equation: 7m+192=13.

12

Solution: Given, 7m+192=13

⇒7m=13-192 (Transposing 192 to R.H.S.)

⇒7m=26-192 ⇒7m=72

On dividing both sides by 7, we get,

⇒7m7=72×17

⇒m=12 Hence, the required answer is 12.

Q.8. Solve and find the value of z: 6z+10=-2.

-2

Solution: Given, 6z+10=-2

⇒6z=-2-10 (Transposing 10 to R.H.S.)

⇒6z=-12 On dividing both sides by 6, we get, ⇒6z6=-126 ⇒z=-2 Hence, the required answer is -2.

Q.9. Find the value of 9l for the equation 3l2=23

4

Solution: Given, 3l2=23

On multiplying both sides by 2, we get,

⇒3l2×2=23×2

⇒3l=43

On dividing both sides by 3, we get,

⇒3l3=43×13

⇒l=49

So, 9l=49×9=4 Hence, 9l=4.

About Class 7 Maths Chapter 4 Simple Equation

Exercise 4.3 of chapter 4 of the NCERT Textbook has an explanation of the concepts and some exercises to assess your understanding of the concept. Simple Equation Chapter 4 of Maths for Class 7 has 22 exercises, and there are 22 questions in Exercise 4.3.

Simple Equation 

A variable and an ‘equal to’ sign make up a simple equation in the simplest of terms. Therefore, a simple equation is a mathematical representation of two expressions on either side of an equal sign. 

It mainly consists of a variable, frequently accompanied by a numerical constant. To understand this concept easily, consider the following example. 

3x – 4 = 5. It is a class 7 simple equation. In this representation, the x refers to a variable. Every equation of this category aims to find the value of x. However, you can also use other letters from the English alphabet to write a variable. 

Furthermore, the value of 3x – 4 must equal 5. As a result, an introductory class 7 equation keeps the same value on both sides of the ‘=’ sign.

You can move any number or variable from one side of the equation to the other in this scenario. Keep in mind that the sign preceding the number changes as well. When a negative integer is shifted to the other side, it becomes a positive integer.

Returning to this equation, you can apply -4 to the other side: 3x = 5+4 = 9.

As a result, x = 9/3 = 3. As a result, the variable x has a value of 3.
