Some one explain this

13

Step-by-step explanation:

The triangles ABC and DEC are the exact same.

That also means that angle b in the same as angle E

You can then do: 3x=6x-39    (because they are the same)

then simplify:

39=3x

x=13

hope this helped! ask questions in the comments if you still don't know.

Make x alone

Subtract 3x on both sides

3x - 3x = 0

6x - 3x = 3x

0 = 3x - 39

Divide 39 by 3

39 / 3 = 13

13 is the answer because it makes the equation equal

Hope this helps
