Question

solve the logarithmic equation.
ln (x-8) - ln (x+7) = ln (x-10) - ln (x+8)

Answer 1

x=-2

Answer 2

use the property.
ln(a)-ln(b)= ln(a/b)

Answer 3

how did you get to -2? thats where i got stuck at

Answer 4

after u use the property, u note that:

(x-8)/(x+7)=(x-10)/(x+8).
solve this equation to get x

Answer 5

ok thanks
