Log(9+9x)-log(11-x) = 2
We can combine the logs, - means divide
log%28%28%289%2B9x%29%2F%2811-x%29%29%29 = 2
Find the antilog of both sides [10%5Ex]
%289%2B9x%29%2F%2811-x%29 = 100
multiply both sides by (11-x)
9 + 9x = 100(11-x)
9 + 9x = 1100 - 100x
9x + 100x = 1100 - 9
109x = 1091
x = 1091%2F109
x = 10.009
