An absolute number usually means you have to consider both the positive and negative number line areas. If you simply remove the absolute sign, 3x = 6 and x=2. On the negative side, a similar equlity occurs with x= -2.

3|x|+4=10
3x+4=10 or -3x+4=10
x=2 or x=-2

Perhaps instead of having us do your homework for you, you should actually try. You won't learn anything this way. Come time for a test, you'll fail. Do your own work -.-
