log3 (x + 6) - log3 (x - 1) = 1
log3 [(x + 6) / (x - 1)] = 1 Law of subtracting logs
31 = (x + 6) / (x - 1) Definition of log
3(x - 1) = (x + 6)
Can you solve for x and aswer?

asked 05/01/20This is the original equation: log3(x+6)-log3(x-1)=1
This is what I've figured out so far:
log3(x+6)-log3(x-1)=1
log3((x+6)(x-1))=1 (combine like expressions)
(x+6)(x-1)=3 (factor log3)
x^2+5x-6=3
x^2+5x-9=0 (simplify to get all expressions on one side)
