# EXERCISE 2.1

Question 1 :

Solve : x – 2=7

sol : x – 2=7

On transposing 2 to R.H.S , we obtain

x = 7 + 2

x = 9

Question 2 :

Solve : y+3=10

sol :

y+3=10

On transposing 3 to R.H.S , we obtain

y= 10 – 3

y = 7

Question 3 :

Solve : 6 =z+2

sol :

6 = z+2

On transposing 2 to L.H.S , we obtain

6-2 = z

z=4

Question 4 :

Solve : ​

sol :

On transposing ​​ to R.H.S , we obtain

= 2

Question 5 :

Solve : 6x=12

sol :

6x=12

Dividing both side by 6 , we obtain

Question 6 :

Solve : ​

sol :

Multiplying both side by 5, we obtain

t=50

Question 7 :

Solve : ​

sol :

Multiplying both side by ​​ , we obtain

x=27

Question 8 :

Solve : ​

sol :

Multiplying both sides by 1.5 , we obtain

2.4=y

Question 9 :

Solve : 7x-9 = 16

sol :

7x-9 = 16

On transposing 9 to R.H.S , we obtain

7x=16+9

7x = 25

Dividing both side by 7 , we obtain

Question 10 :

Solve : ​

sol :

On transposing 8 to R.H.S , we obtain

Dividing both side by 14 , we obtain

Question 11 :

Solve : ​

sol :

On transposing 17 to R.H.S , we obtain

Dividing both side by 6 , we obtain

Question 12 :

Solve : ​

sol :

On transposing 1 to R.H.S , we obtain

Multiplying both sides by 3 , we obtain
