Hi all,

i'm trying to find a solver possibility analogous to the Excel Solver in R.
Since i just started with R, I have only little knowledge. Can someone help
me by solving the problem?

I have the following 'starting position':

z = rnorm(1,0,1)
y <- function(x,z){2*x - 1 + z}

I am looking for a certain "x" in such a way that the result of the function
'y' equals 5.5

Thanks a lot!
