Nested alignments

I want to make alignments that look like this:

enter image description here

which I have done by using

begin{align}

         & frac{dx}{dt} = y qquad frac{dy}{dt} = x \

implies & frac{d^2x}{dt^2} = frac{d}{dt}bigg(frac{dx}{dt} bigg) \

         & ; ; ; ; ; ; , = frac{dy}{dt} \

         & ; ; ; ; ; ; , = x \

implies & frac{d^2x}{dt^2} = x \

implies & x(t) = Ae^t + Be^{-t}

end{align}

Of course, it's kinda silly to do ; ; ; ; ... and align them manually. However, when I try putting a begin{align} within another begin{align} like this

begin{align}

        begin{align}



        end{align}

end{align}

it gives me an error.

What is the correct way of doing this?

EDIT:

begin{alignat} still doesn't quite get me there:

begin{alignat}{2}

         & frac{dx}{dt} = y qquad frac{dy}{dt} = x \

implies & frac{d^2x}{dt^2} && = frac{d}{dt}bigg(frac{dx}{dt} bigg) \

         &                   && = frac{dy}{dt} \

         &                   && = x \

implies & frac{d^2x}{dt^2} = x \

implies & x(t) = Ae^t + Be^{-t}

end{alignat}

gives

You should use alignat rather than align -- alignat allows for multiple & 'columns'

How should I use alignat? There is this massive spacing between the columns

Usually, the & is used before =

I'm not sure why you used upright d's when the OP uses italic ones. Even I conform to ln when the OP does on Math.SE, go figure! ;-)

Nesting align environments directly doesn't work, because align environments start display math, so they can not be used inside math mode. Lucky for you, amsmath includes aligned as an alternative for cases like this (The t tells LaTeX to align the top line with the content outside of the environment):

documentclass{article}

usepackage{amsmath}

begin{document}

begin{align}

         & frac{dx}{dt} = y qquad frac{dy}{dt} = x \

implies & begin{aligned}[t]

             frac{d^2x}{dt^2} &= frac{d}{dt}bigg(frac{dx}{dt} bigg) \

                               &= frac{dy}{dt} \

                               &= x

           end{aligned}\

implies & frac{d^2x}{dt^2} = x \

implies & x(t) = Ae^t + Be^{-t}
