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.

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:

The equation is m/4 = 7+3

⇒ m/4 = 10

⇒ m = 40

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

It implies 1/3m + 5 = 8

QUESTION: 5

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

Solution:

Given that 2x = 12

it implies x = 6

So 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

it implies x = 6 - 4

So x = 2

So 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

7x = 14

Therefore, x = 2

So option A is the correct answer.

QUESTION: 8

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

Solution:

Given equation is :

4x – 3 = 13

4x = 13 + 3

4x = 16

x = 4

So option C is the correct answer.

QUESTION: 9

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

Solution:

The given equation is 5x + 2 = 17

5x = 17 - 2

5x = 15

x = 3

So option C is the correct answer.

QUESTION: 10

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

Solution:

The given equation is 3x - 14 = 4

3x = 18

x = 6

So option A is the correct answer.

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

1/5.x = 7

x = 35

So option D is correct .

QUESTION: 12

Which of the following is not allowed in a given 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 number by zero is not defined.

Note : If we put 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:

5 - p = 3

p = 5 + 3

p = 8

So 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

2x=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

So option D is correct.
