Answer:
Explanation:
Well first we have to take 13 and multiply it be everything in the parentheses.
13(2n - 14) = 712
13*2n - 13* 14 = 712
26n - 182 = 712
Now we take 182 and add it to 712 to get 26n by itself.
26n = 894
Now I believe we divide...
I got 34.38461
I don't know if you can put decimals or if I did this wrong.. Sorry if I did this wrong. If you can put a decimal then you are going to have to round. :)
Hope this is somewhat helpful if not I am truly sorry. Have a wonderful day! :)
