-52.4576 is the correct answer.
ln9^(x+6)=ln7^x
(x+6)*ln(9)=x*ln(7)
(x+6)/x=ln(7)/ln(9)
x/x+6/x=.885622
1+6/x=.885622
6/x=.885622-1
6/x=-.114378
x=6/(-.114378)
x=-52.4576
ln9^(x+6)=ln7^x
(x+6)*ln(9)=x*ln(7)
(x+6)/x=ln(7)/ln(9)
x/x+6/x=.885622
1+6/x=.885622
6/x=.885622-1
6/x=-.114378
x=6/(-.114378)
x=-52.4576
