Math, microeconomics or criminal justice
2|x-2| = 2|2-x| > -15
"difference" usually means a non-negative number, so x could be any real number, as |x-2| is always positive or zero, and always greater than -15. the absolute value of 2(x-2) is always positive or zero, never negative
but if you did consider "difference" as being possibly negative then
2(x-2) > -15
2x -4 > -15
2x > -15+4
2x > -11
x > -11/2
x > - 5.5
or
2(2-x) > -15
4 -2x > -15
-2x > -19
divide or multiply by a negative number reverses the inequality
x < 19/2
x < 9.5
-5.5 < x < 9.5 is the solution that satisfies the inequality, however you interpret the problem
