Answer 1

Answer:

Step-by-step explanation:

Required number = 21

Step-by-step explanation:

Let the number be x.

Twice the number = 2x

Adding 7 to twice the number = 2x + 7

Now , according to the problem given,

Add 7 to twice the number, we get 49

=> 2x + 7 = 49

/* Subtract both side by 7, we get

=> 2x + 7 - 7 = 49 - 7

=> 2x = 42

/* Divide both sides by 2, we get

=> x = 21

Therefore,

Required number = x = 21.

HOPE IT HELPS YOU.

Answer 2

Hi ,

Let the number = x

twice the number = 2x

according to the problem given,

2x + 7 = 49

2x = 49 - 7

2x = 42

x = 42/ 2

x = 21

Therefore ,

Required number = x = 21

I hope this helps you.
