Answer 5

stop spamming others :(

you know the rules used while computing with logarithms?

Answer 6

In this case, you are supposed to:
substract the log11 4
get together the log11 60 and log11 4
get rid of logs
solve simple linear equation.

Answer 7

hint:
using the properties of logarithms, I rewrite the left side of your equation, as below:
\[{\log _{11}}\left[ {4\left( {y + 8} \right)} \right] = {\log _{11}}60\]
namely, the property that I have used is:
\[{\log _{11}}a + {\log _{11}}b = {\log _{11}}\left( {a \times b} \right)\]
