Given the vertices
We know that the intersection of medians brings the centroid of the triangle.
The centroid of a triangle is given by

In this example,



substituting in the formula



Therefore, the coordinates of the centroid are:

The diagram is also attached below.
3z - 7 = 14 |add 7 to both sides
3z = 21 |divide both sides by 3
z = 7
Answer:
