How is it possible to solve the following differential eqiuation using syms and dsolve? I'm quite confused on how to solve dx/dx on matlab. The condition is x(0)=4. Any help would be greatly appreciated.

Double check your assignment. That is probably supposed to be dx/dt, not dx/dx.

Thanks for your reply and your suggestion. The assignment says dx/dx (only 1 task has it like so), so I'll assume its a typo and take it as dx/dt. Thanks again.

Hi,
You can solve the given ODE as follows: -
syms x(t);
ode = 2*diff(x,t) + 7*x == t;
cond = x(0) == 4;
xSol(t) = dsolve(ode,cond);
For more details, check out the following documentation link: -
