differential equations – Simultaneous resolution of EDO or NDSolve

I'm trying to solve sim. ODE as below. I try to use it first Resolution that did not work and NDSolve which also did not work. Anyone can help?

d = 1; r = 4; L = 7; W = 4; w = 2; b = 1;

V[t_,s_]= Exp[(d+r)t]*To integrate[exp[(d+r)*(-x)] (s + d * v[x]), {x, t, 1}

NDSolve[{D[R

)) / (1-Exp[(d+r)(t-1)]),RE[v[v[v[v

and the error message was
