EF is the entire line.

E------G-------F

EG is half the line (or EF is twice as large as EG)

so, EF = 2(EG)
I still don't understand.
EF = 2(EG)
2x+30 = 2 (4x+12)

EG is essentially equal to GF, since G is the midpoint.

once you solve for x, plug it back into 4x+12 and that will give you GF
i got it now, thx!

I came here for answers and im wondering how do you find x if you don't have a full equation since you don't know GF already?
