Question

When 23 is subtracted from 6 times a certain number , the result is 103. What is the number? 

Answer 1

Let the number be x.

 

Translate:

  "23 is subtracted from 6 times a certain number , the result is 103"    means

      - 23                 +    6     *            x                              =   103

 

Re-write:

     6x - 23 = 103

     6x = 126                [add 23 to both sides]

       x = 21                 [divide both sides by 6]
