Class 8 Maths Chapter 2

Question 1:

Solve: 

Answer:

x − 2 = 7

Transposing 2 to R.H.S, we obtain

x = 7 + 2 = 9

Question 2:

Solve: 

Answer:

y + 3 = 10

Transposing 3 to R.H.S, we obtain

y = 10 − 3 = 7

Question 3:

Solve: 

Answer:

6 = z + 2

Transposing 2 to L.H.S, we obtain

6 − 2 = z

z = 4

Question 4:

Solve: 

Answer:

Transposing to R.H.S, we obtain

Question 5:

Solve: 

Answer:

6x = 12

Dividing both sides by 6, we obtain

x = 2

Question 6:

Solve: 

Answer:

Multiplying both sides by 5, we obtain

Question 7:

Solve: 

Answer:

Multiplying both sides by , we obtain

Question 8:

Solve: 

Answer:

Multiplying both sides by 1.5, we obtain

Question 9:

Solve: 

Answer:

7x − 9 = 16

Transposing 9 to R.H.S, we obtain

7x = 16 + 9

7x = 25

Dividing both sides by 7, we obtain

Question 10:

Solve: 

Answer:

14y − 8 = 13

Transposing 8 to R.H.S, we obtain

14y = 13 + 8

14y = 21

Dividing both sides by 14, we obtain

Question 11:

Solve: 

Answer:

17 + 6p = 9

Transposing 17 to R.H.S, we obtain

6p = 9 − 17

6p = −8

Dividing both sides by 6, we obtain

Question 12:

Solve: 

Answer:

Transposing 1 to R.H.S, we obtain

Multiplying both sides by 3, we obtain
