<PRE><B>Question 731975</B>
Twice the difference between a number, n, and thirty-one is three times the number. How do I translate n solve this problem?
--------------
The difference between a number, n, and thirty-one can be n-31 or 31-n.
The absolute value, |n-31|, covers both.
-----
2|n-31| = 3n
2n-62 = 3n
n = -62
-----------
2(31-n) = 3n
62 - 2n = 3n
5n = 62
n = 12.4
