Final answer:
There is no value of x that satisfies the given equation.
Step-by-step explanation:
To find x, we can set the two medians, EC and DC, equal to each other since they intersect at point D.
Therefore, 3x+9 = 3x-6.
Let's solve for x:
- 3x+9 = 3x-6
- Subtract 3x from both sides: 9 = -6
- This is not possible since 9 is not equal to -6. Hence, there is no solution for x.
Therefore, there is no value of x that satisfies the given equation.
