**Charrice**, Monday, August 27, 2012 at 10:25pmLet x = number in ones place

Let x + 2 = number in tens place

Let x - 4 = number in hundreds place

add all and set equal to 16

x + x+2 + x-4 = 16

x + x + x = 16 -2 + 4

3x = 18

divide both sides by 3

3x/3 = 18/3

x = 6

Answer = three digit number is 286
