Question

1. the solution of the equation 3 n - 2 = 46 is n =
2. solution of the equation is 5 m + 7= 17 is m =
3. the sum of three times a number and 11 is 32 . find the number.​

Answer 1

Answer:

1). Solution of equation 3n - 2 = 46

=> 3n = 46 + 2

=> 3n = 48

=> n = 48/3

=> n = 16

Therefore, solution of this equation is 16.

2). Solution of equation 5m + 7 = 17

=> 5m = 17 - 7

=> 5m = 10

=> m = 10/5

=> m = 2

Therefore, solution of this equation is 2.

3). Sum of three times a number and 11 is 32.

=> 3x + 11 = 32 [ here x refers to a number ]

=> 3x = 32 - 11

=> 3x = 21

=> x = 21/3

=> x = 7

Therefore, required number is 7.

Answer 2

Answer:

Step-by-step explanation:

Answer 1

Given :-

Solution of equation 3n - 2 = 46

Solution :-

⇒ 3n = 46 + 2

⇒ 3n = 48

⇒ n = 48/3

⇒ n = 16

Hence, solution of this equation is 16.

Answer 2

Given :-

Solution of equation 5m + 7 = 17

Solution :-

⇒ 5m = 17 - 7

⇒ 5m = 10

⇒ m = 10/5

⇒ m = 2

Hence, solution of this equation is 2.

Answer 3

Given :-

Sum of three times a number and 11 is 32.

Solution :-

⇒ 3x + 11 = 32

⇒ 3x = 32 - 11

⇒ 3x = 21

⇒ x = 21/3

⇒ x = 7

Hence, required number is 7.
