system of equation solving plot

pl solve this system of equation by power series method help is highly appreciate

this is system of differential equation plot x vs t

y vs t

why question is close if any one is not interested do not answer

[shiv gaur]

this the equation after power series solving

x(0)=1;

y(0)=0

t=1:100;

for n=1:15

x(n+1)=(x(n-1)-y(n))/n+1;

y(n+1)=(x(n)+y(n)-t)/n+1

end

plot(t,x)

now how to plot
