Because they are coupled equations. thanks for your help. You can use the standard differential equation solving function, NDSolve, to numerically solve delay differential equations with constant delays. It returns an interpolation function that can then be easily used with other functions.

In the most general form, an Nth order ordinary differential equation (ODE) of a single-variable function $y(x)$ can be expressed   of first-order differential equations, no general formula can be used to solve them… by japh.

It's not that MATLAB is wrong, its solving the ODE for y(x) or x(y). Exact differential equations is something we covered in depth at the graduate

A general first-order differential equation is given by the expression: dy/dx + Py = Q where y is a function and dy/dx is a derivative. The solution of the linear differential equation produces the value of variable y.

Solving. We solve it when we discover the function y (or set of functions y). There are many "tricks" to solving Differential Equations (if they can be solved Bernoulli Differential Equations – In this section we solve Bernoulli differential equations, i.e.
