QUESTION: 1

Write the statements “The sum of three times x and 11 is 32” in the form of equations:

Solution:

The sum of three times x and 11 is 32.

⇒ 3x + 11 = 32

QUESTION: 2

Write the statements “If you subtract 5 from 6 times a number, you get 7” in the form of equations:

Solution:

Let us say the number is x;

⇒ x multiplied by 6 is 6x.

On Subtracting 5 from 6x, one gets 6x – 5.

∵ The result is 7.

∴ The equation is 6x – 5 = 7

QUESTION: 3

Write the statements “One fourth of m is 3 more than 7” in the form of equations:

Solution:

__Let's approach the statement stepwise:__

One-fourth of m = m/4

And, 3 more than 7 will be 3 + 7

Now equating both sides,

m / 4 = 3 + 7

QUESTION: 4

Write the statements “Product of One third of a number and m plus 5 is 8” in the form of equations:

Solution:

One-third of a number plus 5 is 8

⇒ (1/3) m + 5 = 8

QUESTION: 5

Which is a solution of the equation 2x = 12?

Solution:

Given that, 2x = 12

⇒ x = 6

∴ x = 6 is the solution of the given equation

QUESTION: 6

Which is a solution of the equation x + 4 = 6?

Solution:

Given equation is x + 4 = 6

⇒ x = 6 - 4 = 2

∴ Option C is the correct answer.

QUESTION: 7

Which is a solution of the equation 7x + 5 = 19?

Solution:

Given equation is 7x + 5 = 19

⇒ 7x = 19 - 5 = 14

⇒ x = 2

QUESTION: 8

Which is a solution of the equation 4x – 3 = 13?

Solution:

Given equation is 4x – 3 = 13

⇒ 4x = 13 + 3 = 16

⇒ x = 4

QUESTION: 9

Which is a solution of the equation 5x + 2 = 17?

Solution:

The given equation is 5x + 2 = 17

⇒ 5x = 17 - 2 = 15

⇒ x = 3

QUESTION: 10

Which is a solution of the equation 3x – 14 = 4?

Solution:

The given equation is 3x - 14 = 4

⇒ 3x = 18

⇒ x = 6

QUESTION: 11

One - fifth of a number minus 4 gives 3. Find which of the following is the number?

Solution:

Let the number be x.

According to question,

(1/5) x - 4 = 3

⇒ (1/5) x = 4 + 3 = 7

⇒ x = 35

QUESTION: 12

Which of the following is not allowed in any equation?

**(a)** Adding the same number to both sides of the equation.

**(b)** Subtracting the same number from both sides of the equation.

**(c)** Multiplying both sides of the equation by the same non-zero number.

**(d)** Dividing both sides of the equation by the same number.

Solution:

Dividing both sides of the equation by the same non-zero number is allowed in a given equation.

∵ Division of any number by zero is not allowed as set division of a number by zero is not defined.

Note: If we put the same number to both sides of the equation while adding or subtracting, then there will be no change in the given equation.

QUESTION: 13

Subtracting 5 from p , the result is 3. What is the value of p?

Solution:

∵ p - 5 = 3

⇒ p = 5 + 3 = 8

Therefore, value of p = 8

QUESTION: 14

13 subtracted from twice a number gives 2. What is the number?

Solution:

Let the number be x.

According to question,

2x - 13 = 2

⇒ 2x = 2 + 13 = 15

⇒ x = 15/2

QUESTION: 15

5 times a number increased by 5 is 25. What is the number?

Solution:

Let the number be x

__According to question:__

⇒ 5x + 5 = 25

⇒ 5x = 20

⇒ x = 4
