Can you help me?

True or False, if False correct the underlined portion.

1) If 3<x, then 3+y<x+y

2)If |w-7|<-3, then w-7>-3 or w-7<3

3) If -4<-2t+6<10, then 2>t+6>-5

4) If |y+8|+2=6, then y+8=+-4*

* the "+" is on top of "-", I didn't know how to type it in.

I would really appreciate the help.

**Damon**, Sunday, September 23, 2012 at 8:27pm1 is true

2 makes no sense/ an absolute value can not be negative.

3 but t = 0 ok for first but not for second

4 you mean

4) If |y+8|+2=6, then y+8=+/- 4

y + 8 + 2 = 6

then y = -4

-(y+8) + 2 = 6

-y - 8 + 2 = 6

- y - 6 = 6

-y = 12 NO or false
