point G is the midpoint of EF EG= 4x+12 and EF= 2x+30. How do i find GF?

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?
To find the length of GF, we need to use the fact that point G is the midpoint of line segment EF.
Since G is the midpoint, we can set up the equation:
GF = EF - EG
But we need to find the values of EF and EG in terms of x first. Given that EG = 4x + 12 and EF = 2x + 30, substitute these values into the equation:
GF = (2x + 30) - (4x + 12)
Let's simplify this expression:
GF = 2x + 30 - 4x - 12
Combine like terms:
GF = -2x + 18
So, GF is equal to -2x + 18.
