What is the value of x? <br><br> Enter your answer in the box.
Svetlanka [38]

Answer: x = 3


Step-by-step explanation:

Note that this triangle has 3 congruent angles. Therefore, it is an equilateral triangle. So, the sides will also be congruent.

So it can be said that : 6x - 3 = 3x + 6

+3

6x = 3x +9

-3x

3x = 9

/3

x = 3

By replacing x with 3, we can prove that these expressions all equal 15.

6(3) -3 = 18 - 3 = 15 . 3(3) + 6 = 9 + 6 = 15  . 5(3) = 15
