2|x-1|
= twice the difference of a number and 1
or
2(x-1) = 2x-2
but it could also be
2(1-x) = 2-2x
using the absolute value sign instead of parentheses captures both
the difference of x and 1 which could be x-1 or 1-x,
the "difference" is usually treated as positive
regardess whether 1 or x is the larger
