Question

If we add 7 to twice a number, we get 49. Find the number.​

Answer 1

Answer:

let the number be x

3x+7=49

3x=49-7

3x=42

x=14

Answer 2

Let the given number be x

Therefore by given condition

2x + 7 = 49

2x = 49 - 7

2x = 42

x = 42 / 2

x = 21

Thus the number is 21

( Verification :

2x + 7 = 49 and x = 21

2(21) +7 = 49

42 + 7 = 49

49 = 49 )
