ABC = EDF. Determine the value of x.
astra-53 [7]

Answer:

The correct answer here is A. x = 17.

How I found this out:

3x + 3 and 5x - 7 are going to be different solutions in the end.  

I did the process of elimination.

First, I subsituted, 17 for x. 3 X 17 + 3 = 54. 5 X 17 - 7 = 78.

I then took 180 - 54 - 48 = 78 and 180 - 78 - 48 = 54, just to make sure they are positive numbers and not negative.

Since they work out, I chose this as my correct answer to your question.  

Step-by-step explanation:

Hope this helps! :)

I tried my best so I'm it's wrong.
