:roll:
I am having a problem on -8 + ln 4x=2.5
-8 -8
-------------------------------------------------
ln (4x)=-2.5/8

e^ln(4x)= e^-2.5/8
4x= e ^-2.5/8
x= e^-2.5/8 over 4
I GOT 0.1829 BUT THAT WAS WRONG, PLEASE POINT ME IN RIGHT DIRECTION

It appears you divided both sides by 8. You should add 8 to both sides.
