Question

point g is the centroid of triangle ABC
find value of x, FG=x+8 and AF=9x-6

Answer 1

I guess you forgot to say where F is.

Answer 2

For the question to be "workable", AF is probably the median, with F on BC

remember the centroid cuts the median in the ratio of 2:1, or AG:GF = 2:1
then FG:AF = 1:3
(x+8)/(9x-6) = 1/3
9x - 6 = 3x + 24
6x = 30
x = 5
