    is the original supposed to be sec(pi)(2x+1) = 2?

    That doesn't make any sense. You have two "(" and only one ")".
    The whole question is whether you mean sec(pi(2x+1))= 2 or sec(pi(2x)+ 1= 2 and you still haven't answered that.

    sec(pi(2x+1))= 2 is what i mean.

    So cos(pi(2x+1)) = ? Does that suggest an easier way to search for the values of x?
