If 33 is added to a number and the sum is tripled, the result is 15 more than the number. Find the number

Question

(33+x)3=15+x

Answer 1

 

  Let x = be the number

 

 

  3 ( x + 33 ) = x + 15  is the equation

 

  Solving for x:

 

    3x + 99 = x + 15

 

           2x = - 84

 

              x = -42

 

To check: 

 

          3 ( -42 + 33 ) = -42 + 15

 

                   3 ( -9 ) = -27

 

                        -27 = -27
