log3(5)+log3x=log3(10)
=> log3 (5 X 3x ) =log3(10)
=>log3(15x) =log3(10)
=>15x=10
=>x=2/3

i think u did a mistake some where @DHASHNI \[\large{log_3(5)+log_3(x)=log_3(5*x)}\]but it is given equal to \(\large{log_3{10}}\)
\(\large{\log_3(5x)=log_3(10)}\)
\(\large{5x=10}\)
\(\large{x=\frac{10}{5}=2}\)

Use the property\[\LARGE{\log_{n}{a}+\log_{n}{b}=\log_{n}{a+b}} \]
