• If 5 is subtracted from 3 times a number , then the result is 7 .

To find :

• The number

Solution :

• Let the number be x

According to Question Given that,

• 5 is subtracted from 3 times a number and result is 7

• Then 3 times a number be 3x

Substituting the value :

↬ 3x - 5 = 7

↬ 3x = 7 + 5

↬ 3x = 12

↬ x = 12/3

↬ x = 4

Hence

The number is 4.

Verification :

↬ 3x - 5 = 7

↬ 3(4) - 5 = 7

↬ 12 - 5 = 7

↬ 7 = 7

Hence , Verified
