(                    )




10)  

If 5 ( x - 6) = 25, then x is ______






(                    )




 

1)  

  x5 = 14, then x is ____





Answer: 4


SOLUTION 1 :

  x5 = 14 

5 x x5 = 5x14          ( multiplying by 5 both sides )

⇒ x = 70



2)  

 Choose the correct answer : 

If r+3 = 12, r is ____





Answer: 2


SOLUTION 1 :

   r+3 = 12             ( on transposing +3 becoes - 3)

    ⇒ r = 9



3)  

Slove:

p- 3 = 9

p =   Answer: 12


SOLUTION 1 :

Slove

⇒ p = 3+9   ( on transposing  - 3 becomes + 3 )

⇒ p = 12

 



4)  

 Choose the correct answer : 

If 12 - g = 3, g is ____





Answer: 3


SOLUTION 1 :

      12 -g = 3             ( on transposing +3 becomes - 3)

   ⇒-g = - 9             ( cancelling  - both sides )

   ⇒ g = 9



5)  

If 8 ( y - 7) = 24, then y is ______





Answer: 2


SOLUTION 1 :

Slove:

8 ( y - 7) = 24, 

8 (y - 7) / 8 = 248   ( Dividing by 8 on both sides).

⇒ y - 7 = 3

⇒ y = 3 - 7 = -4



6)  

  y4 = 9, then y is ____





Answer: 1


SOLUTION 1 :

  y4 = 9 

4 x y4 = 4x9          ( multiplying by 4 both sides )

⇒ y = 36



7)  

 Choose the correct answer : 

If d+2 = 14, d is ____





Answer: 2


SOLUTION 1 :

   d+2 = 14             ( on transposing +2 becoes - 2)

    ⇒ d = 12



8)  

Slove:

j- 6 = 9

j =   Answer: 15


SOLUTION 1 :

Slove

⇒ j = 6+9   ( on transposing  - 6 becomes + 6 )

⇒ j = 15

 



9)  

 Choose the correct answer : 

If 12 - l = 2, l is ____





Answer: 4


SOLUTION 1 :

      12 -l = 2             ( on transposing +2 becomes - 2)

   ⇒-l = - 10             ( cancelling  - both sides )

   ⇒ l = 10



10)  

If 5 ( x - 6) = 25, then x is ______





Answer: 2


SOLUTION 1 :

Slove:

5 ( x - 6) = 25, 

5 (x - 6) / 5 = 255   ( Dividing by 5 on both sides).

⇒ x - 6 = 5

⇒ x = 5 - 6 = -1
