I have the equations as follows
and
What I have to do is integrate and supply the output to sumlatenously at each time step as gets integrated and this must happen in a speciafic time inteval.
Is there a way to do in code?
Eg - If gets integrated from 0 to witha a constant θ and at time , the value of theta must be taken from intgrated . This must happen simultaneously.

Use the "Nonstiff Euler Equations" example on this documentation page as a model for your ODE function.

You have a system of two differential equations. Solve them simultaneously just like that example solves three differential equations simultaneously.

Your theta equation is independent of x, so you could integrate this separately (in fact, it has an analytical solution), then use the result in the x integration routine.
