**Steve**, Friday, January 25, 2013 at 11:43amA little thought should make it clear that since x is farther from 11 than from 19,

1. x is between 11 and 19

2. x > 19

If 11<x<19,

x-11 = 3(19-x)

x-11 = 57-3x

4x = 68

x = 17

If x > 19,

x-11 = 3(x-19)

x-11 = 3x-57

2x = 46

x = 23

check:

17 is 6 from 11 and 2 from 19

23 is 12 from 11 and 4 from 19
