Logs!!!!

Hey guys
In C2 for logarithms how do you manipulate a question with three minus logs??
Coz I know that when there's a minus you divide the logs but how do you do that if there are three minuses??
Ex: log(2)11x+3 - log(2)5x - 2log(2)x = 1

Please help 😭😭😭

log(x)-log(y)=log(x/y)
log(x/y) - logz = log(x/yz)

Take it step by step remember you cannot do the following 2log(x) - log(y) = 2log(x/y) noooo
2log(x) -log(y) = Log(x^2/y)

−log⁡ab=log⁡a(1b) -\log_ab=\log_a\left ( \frac{1}{b} \right ) .
