Answer 2

Answer:

The required number is 3. If 2 is subtracted from thrice of a number result is 7.  

Step-by-step explanation:

• Let x be the required number.

         As per the given data,

         2 is subtracted from thrice of a number results to 7.

       Now,  thrice of the required number x = 3x

                 2 is subtracted from the thrice of number = 3x - 2

        Now, the above expression results to 7

             So, 3x-2 = 7

                       3x = 7+2

                       3x = 9

                         x = 3

          Hence the required number is '3'.
