For this question you can say: log(x-2) - log(x+1) = -1 and you should know that log(x-2) minus log(x+1) is equal to: log((x-2)/(x+1)) so now you have: log((x-2)/(x+1)) = -1 now you can say: (x-2)/(x+1) = 10^ -1 or (x-2)/(x+1) = 1/10 now you can say: 10(x-2) = x+1 10x -20 = x +1 10x - x = 20+1 9x = 21 x = 21/9 x = 7/3 :))) I hope this is helpful have a nice day
