When 47 is added to a number the result is 37 less than 7 times the number

47 is added to a number ⇒ 47 + x

37 less than 7 times the number ⇒ 7x - 37

47 + x = 7x - 37

x - 7x = - 37 - 47

- 6x = - 84

x = - 84 / - 6

x = 14

The value of the unknown number is 14.

47 + x = 7x - 37

47 + 14 = 7 (14) - 37

61 = 98 - 37

61 = 61
