|3k - 2| = 2|k + 2|
3k - 2 = 2|k + 2| or 3k - 2 = -2|k + 2|
(3k - 2)/2 = |k + 2| or (3k - 2)/-2 = |k + 2|
(3k - 2)/2 = k + 2 or -(3k - 2)/2 = k + 2 or -(3k - 2)/2 = k + 2 or (3k - 2)/2 = k + 2
3k - 2 = 2(k + 2) or -3k + 2 = 2(k + 2)
3k - 2 = 2k + 4 or -3k + 2 = 2k + 4
3k - 2k = 4 + 2 or 2k + 3k = 2 - 4
k = 6 or 5k = -2
k = 6 or k = -2/5
