17 less than 12 times a certain number (m) IS 23 less than six times the same
REY [17]

Answer:

  m = -1

Step-by-step explanation:

12 times the number is 12m

17 less than that is 12m -17.

23 less than 6 times the number is 6m-23.

These expressions  are said to be the same:

  12m -17 = 6m -23

  6m -17 = -23 . . . . . . . . subtract 6m from both sides

  6m = -6 . . . . . . . . . . add 17 to both sides

  m = -1 . . . . . . . . . divide both sides by 6

The value of m is -1.
