Homework Equations
If you use ti-89 titanium, you write log with base(b) (c=number) as log(c,b) fx; the log of 3x in base 5 is written log(3x,5) (log5(3x))took me forever to figure out
The Attempt at a Solution
I filled out about 5 handwriten papers with attempts, all which failled. don't force me to write all my attempts since i find this to be very tedius.
simplified, the equation is;
10*5x=3*5-x+1
i put log5 on each side geting:
log5(5x+3)-x=x+log5(10)
then moving it about a bit i get:
2x-log5(5x+3)=log5(10)
But here i get stuck...
