| 2) Slove: 6x = 36 + 4x x = Answer:_______________ |
| 3) Slove: -2y = - 6y + 24 y = Answer:_______________ |
| 4) Slove: 4x = 33 - 7x x = Answer:_______________ |
| 5) Slove: 9y = 24 + 3y y = Answer:_______________ |
| 6) Slove: -2x = - 8x + 12 x = Answer:_______________ |
| 7) Slove: 3x = 16 - 5x x = Answer:_______________ |
| 8) Slove: 8y = 15 + 3y y = Answer:_______________ |
| 9) Slove: -3y = - 7y + 16 y = Answer:_______________ |
| 10) Slove: 3x = 18 - 6x x = Answer:_______________ |
| 1) Slove: 4y = 30 - 6y y = Answer: 3 SOLUTION 1 : Slove: 4y = 30 - 6y 4y + 6y = 30 ( on transposing - 6 becomes +6 ) ( 4 + 6 )y = 30 10y = 30 ( multiplying by 10, both the sides )
⇒ y = 3.
|
| 2) Slove: 6x = 36 + 4x x = Answer: 18 SOLUTION 1 : Slove: 6x = 36 + 4x 6x - 4x = 36 ( on transposing + 4 becomes - 4 ) ( 6 - 4 )x = 36 2x = 36 ( multiplying by 2, both the sides )
⇒ x = 18.
|
| 3) Slove: -2y = - 6y + 24 y = Answer: 6 SOLUTION 1 : Slove: - 2y = - 6y + 24 - 2y + 6y = 24 ( on transposing - 6 becomes + 6 ) ( - 2 + 6 ) y = 24 4y = 24 ( multiplying by 4, both the sides )
⇒ y = 6.
|
| 4) Slove: 4x = 33 - 7x x = Answer: 3 SOLUTION 1 : Slove: 4x = 33 - 7x 4x + 7x = 33 ( on transposing - 7 becomes +7 ) ( 4 + 7 )x = 33 11x = 33 ( multiplying by 11, both the sides )
⇒ x = 3.
|
| 5) Slove: 9y = 24 + 3y y = Answer: 4 SOLUTION 1 : Slove: 9y = 24 + 3y 9y - 3y = 24 ( on transposing + 3 becomes - 3 ) ( 9 - 3 )y = 24 6y = 24 ( multiplying by 6, both the sides )
⇒ y = 4.
|
| 6) Slove: -2x = - 8x + 12 x = Answer: 2 SOLUTION 1 : Slove: - 2x = - 8x + 12 - 2x + 8x = 12 ( on transposing - 8 becomes + 8 ) ( - 2 + 8 ) x = 12 6x = 12 ( multiplying by 6, both the sides )
⇒ x = 2.
|
| 7) Slove: 3x = 16 - 5x x = Answer: 2 SOLUTION 1 : Slove: 3x = 16 - 5x 3x + 5x = 16 ( on transposing - 5 becomes +5 ) ( 3 + 5 )x = 16 8x = 16 ( multiplying by 8, both the sides )
⇒ x = 2.
|
| 8) Slove: 8y = 15 + 3y y = Answer: 3 SOLUTION 1 : Slove: 8y = 15 + 3y 8y - 3y = 15 ( on transposing + 3 becomes - 3 ) ( 8 - 3 )y = 15 5y = 15 ( multiplying by 5, both the sides )
⇒ y = 3.
|
| 9) Slove: -3y = - 7y + 16 y = Answer: 4 SOLUTION 1 : Slove: - 3y = - 7y + 16 - 3y + 7y = 16 ( on transposing - 7 becomes + 7 ) ( - 3 + 7 ) y = 16 4y = 16 ( multiplying by 4, both the sides )
⇒ y = 4.
|
| 10) Slove: 3x = 18 - 6x x = Answer: 2 SOLUTION 1 : Slove: 3x = 18 - 6x 3x + 6x = 18 ( on transposing - 6 becomes +6 ) ( 3 + 6 )x = 18 9x = 18 ( multiplying by 9, both the sides )
⇒ x = 2.
