C3 Iteration Chapter 4 help.

Hi guys, I know how to iterate and feel confident doing that.
But need help on a couple of re-arranging equation questions from the exercise book.

Q6 - how to rearrange e^0.8x- 1/3-2x = 0 to be written as
i) x=1.5 - 0.5e^-0.8xii) p ln(3-2x) stating the value of p

and

Q9 - show that 2^1-x =4x+1 can be arranged to x=1/2(2^-x)+q

Many thanks.
