Test: Simple Equations - Question 1

Write the statement “One-fourth of m is 3 more than 7” in the form of an equation:

Detailed Solution for Test: Simple Equations - Question 1

Let's approach the statement stepwise:
► One-fourth of m = m/4
► 3 more than 7 will be 3 + 7

Equating both sides, m/4 = 3 + 7

Test: Simple Equations - Question 2

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

Detailed Solution for Test: Simple Equations - Question 2
- We start with the equation: 4x – 3 = 13.
- To isolate 4x, we add 3 to both sides: 4x = 13 + 3.
- This simplifies to: 4x = 16.
- Next, we divide both sides by 4 to solve for x: x = 16 / 4.
- Therefore, x = 4.
- The correct answer is option 3: x = 4.

Test: Simple Equations - Question 3

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

Detailed Solution for Test: Simple Equations - Question 3

Let the number be x.
Equation: 2x - 13 = 2
⇒ 2x = 2 + 13 = 15
⇒ x = 15/2

Test: Simple Equations - Question 4

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

Detailed Solution for Test: Simple Equations - Question 4

Given that, 2x = 12
⇒  x = 6 

Test: Simple Equations - Question 5

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

Detailed Solution for Test: Simple Equations - Question 5

Let the number be x 
Equation: 5x + 5 = 25 
⇒ 5x = 20 
⇒ x = 4

Test: Simple Equations - Question 6

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

Detailed Solution for Test: Simple Equations - Question 6

Let the number be x.
Equation: (1/5) x - 4 = 3 
⇒ (1/5) x = 4 + 3  = 7 

⇒ x = 7x5
⇒ x = 35

Test: Simple Equations - Question 7

Write the statement “The sum of three times x and 11 is 32” in the form of an equation:

Detailed Solution for Test: Simple Equations - Question 7

The sum of three times x and 11 is 32.
⇒ 3x + 11 = 32

Test: Simple Equations - Question 8

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

Detailed Solution for Test: Simple Equations - Question 8

Test: Simple Equations - Question 9

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.

Detailed Solution for Test: Simple Equations - Question 9

Division of any number by zero is not allowed, therefore dividing both sides of the equation by the same non-zero number is allowed in a given equation.

Test: Simple Equations - Question 10

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

Detailed Solution for Test: Simple Equations - Question 10

Given that, 5x + 2 = 17
⇒ 5x = 17 - 2 
⇒ 5x = 15
⇒ x = 3

Test: Simple Equations - Question 11

Write the statement “Product of One-third of a number 'm' plus 5 is 8” in the form of an equation:

Detailed Solution for Test: Simple Equations - Question 11

One-third of a number plus 5 is 8
⇒ (1/3) m + 5 = 8 

Test: Simple Equations - Question 12

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

Detailed Solution for Test: Simple Equations - Question 12

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

Test: Simple Equations - Question 13

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

Detailed Solution for Test: Simple Equations - Question 13

Given that, 7x + 5 = 19
⇒ 7x = 19 - 5 = 14 
⇒  x = 2

Test: Simple Equations - Question 14

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

Detailed Solution for Test: Simple Equations - Question 14

Given that,  x + 4 = 6
⇒ x = 6 - 4 = 2

Test: Simple Equations - Question 15

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

Detailed Solution for Test: Simple Equations - Question 15
Answer: 1. 8
  • Start with the equation: p - 5 = 3
  • Add 5 to both sides to isolate p: p = 3 + 5
  • Calculate the sum: p = 8

Therefore, the value of p is 8.
