Answer:

[tex]x=-\frac{9ln(15)}{2ln(11)-ln(15)}[/tex]

Step-by-step explanation:

[tex]11^{-2x}=15^{x+9}[/tex]

[tex]e^{(-2x)ln(11)}=e^{(x+9)ln(15)[/tex]

[tex]-2xln(11)=(x+9)ln(15)[/tex]

[tex]-2xln(11)=xln(15)+9ln(15)[/tex]

[tex]-2xln(11)-xln(15)=9ln(15)[/tex]

[tex]x(-2ln(11)-ln(15))=9ln(15)[/tex]

[tex]x=\frac{9ln(15)}{-2ln(11)-ln(15)}[/tex]

[tex]x=-\frac{9ln(15)}{2ln(11)-ln(15)}[/tex]
