Answer:
n=18
Step-by-step explanation:
100=4(n+7)
100=4n+28
-28 -28
72=4n
n=18
In case this wasn't easy to understand, first you distribute the 4 to the n and 7, to get 28, after that the equation becomes 100=4n+28, then you subtract 28 from 100, and from itself to get the 4n by itself, you are left with 72=4n, after that you just divide 4n and 72 by 4 and get n=18
hope that helped :)
