uhh if GH is 1 line, and D is the midpoint...and if GH= 4x-1, and D=8 then shouldnt GH's value be 16? making it uhh x=3.75 or 3 3/4..Right?

GH = 4x - 1
D = GH/2 = (4x - 1)/2 = 8
4x - 1 = 16
4x = 17
x = 17/4 = 4.25

If D is 8 on a number line and it is also the midpoint of some line segment called GH, then all we can say is that D is halfway between G and H. We know that GH = 4x-1 but that does not tell us where either G or H is. They could be anywhere.
G could be 6 and H could be 10 and 8 would be the midpoint.
G could be 7 and H could be 9 and 8 would be the midpoint
You are missing some data neede to solve this problem.

how can D equal 8? a midpoint can't be a number. a line segment can. is that what you mean? GD or DH is 8? if so then yeah, GH is 16. and that would make x equal 4.25.

4x-1 = 16
4x = 17
x = 4.25
