8x-4= (2x+4)+(2x+4)+(2x+4)

Answer:

x = 8

Explanation:

Since C is the centroid, then

CP =
(1)/(3) JP , that is

2x + 4 =
(1)/(3) (8x - 4) ( multiply through by 4 to clear the fraction )

6x + 12 = 8x - 4 ( subtract 8x from both sides )

- 2x + 12 = - 4 ( subtract 12 from both sides )

- 2x = - 16 ( divide both sides by - 2 )

x = 8
