x=-47.6 ================================== Before the supervisor starts to complain about detail, I'll show that man's work: 380 - 9x = x - 96 380 - 10x = -96 - 10x = - 96 - 380 = - 476 X = + 47.6 . Whoops. I got a different answer. Let's check my solution. Substitute it in the original equation: 380 - 9(47.6) ?=? 47.6 - 96 380 - 428.4 ?=? - 48.4 - 48.4 ?=? - 48.4 Yes ! The first contributor's answer above was wrong by its sign. X = + 47.6
