Answer:

The answer to your question is: x = 3

Step-by-step explanation:

This is an equilateral triangle so let's work with side AB and AC

                               6x - 3 = 3x + 6

                               6x - 3x = 6 + 3

                               3x = 9

                              x = 9 / 3

                              x = 3
