hello i am having this set of 4 differential first order equations : ode1(t) =
diff(x(t), t) == (36552913157447*x(t))/17179869184
diff(x(t), t) == -(3598384661667177*x(t))/2199023255552
diff(x(t), t) == 87500*x(t) + 12000
diff(x(t), t) == -89000*x(t)
now when I type : solver = solve(ode1,t)
i get :
solver =
Empty sym: 0-by-1
what to do ?

syms x(t)
eqn = diff(x, t) == (36552913157447*x)/17179869184 ;
sol = dsolve(eqn)
Same for the other differential equations.
Best wishes

Look at the example in the link and you'll see how to proceed.

the problem in the link that u send me , is that the equations that i need to solve i get in the command window unlike in the link that u sent me i write the equations in the editor
