I'm in need of help with some of the problems, it would be nice if you could explain how to solve them!

1. If XT = 12 and XZ = 21, then TZ = ____
2. If XZ = 3x, XT = x + 3, and TZ = 13, find XZ.
3. Suppose that T is the midpoint of segment XZ
If XT = 2x + 11 and XZ = 5x + 8, find the value of x.

I will donate 25k vbux if you're willing to help me solve these questions!.

1. 21 - 12 = 9 = TZ
2. ???
3. 3x = 3, x=1

No need to donate. Good luck with number 2.

Thanks for the help, but could you possibly explain how to solve them?

2. ???

3. Suppose that T is the midpoint of segment XZ. If XT = 2x + 11 and XZ = 5x + 8, find the value of x.

2)
XZ = XT + TZ

3x = x + 3 + 13

3x = x + 16

2x = 16

x = 8

XZ = 3x

XZ = 3*8

XZ = 24

Don't worry about the vBux

Oh thanks dude, I understand it now. Could you ever help me with geometry if I need it again possibly?

Of course, just PM or VM me

Ahh cool thanks man, I'll try not to bother you with my Geometry work .

haha, Feel free though I'm wanting to keep fresh over the summer :p
