solve for x
12000(1-0.06)^x=8000
--------------
(1-0.06)^x=8000/12000 = 2/3

x*log(0.94) = log(2/3)
x = log(2/3)/log(0.94)
Was that hard?

solve for x
12000(1-0.06)^x=8000
-----------------------------
0.94^x = 8/12
-------
0.94^x = 2/3
-------
x*log(0.94) = log(2/3)
-------
x = log(2/3)/log(0.94)
-------
x = 6.5529
