ordinary differential equations

I have a set of ode something like

x={x1,x2}

x1_dd=f(x2_dd)
and
x2_dd=g(x1_dd)

While this can be solved using standard ode45 prodcedure such as

dx(1)=x(2);
dx(2)=f(dx(4))
dx(3)=x(4);
dx(4)=g(dx(2))

I am not sure if it is right from numerical methods perspective because I have LHS of second equation in RHS of first and vice versa.

Any thoughts on this would be appreciaetd.
