Question

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

number (m). Solve for the value of 'm'.

Answer 1

m = -1

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.
