Please help! I'm not sure what the answer is! What is the value of X?

OpenStudy (anonymous):

Here is the picture!

OpenStudy (abb0t):

x has a lot of value! don't be mean to x!

OpenStudy (anonymous):

So what's the value then?

OpenStudy (anonymous):

They are vertical angles, so you set them equal to each other and solve.

OpenStudy (anonymous):

Okay so I got 55. I just want to make sure I got the right answer.

OpenStudy (anonymous):

Did you have this to solve: \[7x-8=6x+11\]

OpenStudy (anonymous):

yes I did.

OpenStudy (anonymous):

Did you get 55 for x or for the degrees?

OpenStudy (anonymous):

For X, but I'm not sure if it's the right answer.

OpenStudy (anonymous):

Not yet. With the equation you want to first move the variable to one side. \[7x-8-6x = 6x-6x+11\] \[x-8=11\] Did you get this?

OpenStudy (anonymous):

Yes. I'm with you so far. what's next?

OpenStudy (anonymous):

Next you will move the 8 to the other side. So what do you get when you add 8 to both sides?

OpenStudy (anonymous):

Well adding 8 to -8 gives me zero and adding 8 to 11 gives me 19. Is that right?

OpenStudy (anonymous):

Yes, x=19. Now make sure you read the question carefully to determine if you need to find x or the degree measure of the angle.

OpenStudy (anonymous):

I think I can take it from here. Thanks to much for your help and patience. I really appreciate it.
