log (2x-2) = log (x-2) + 1
we will
use logarithm properties to find the value of x.
First we know that
log 10 = 1
==> log (2x-2) = log (x-2) + log
10
Now we know that log a + log b = log
ab
==> log (2x-2) = log
(10*(x-2)
==> log (2x-2) = log (10x
-20)
Now, we know that if log a = log b ==> a =
b
==> (2x-2) = 10x
-20
==> 8x = 18
==> x =
18/8= 9/4= 2.25
Then the solution to the equation is
9/4 = 2.25.
