Question: i want to solve couple differential equation with ode analyzer but i get error

hi . i want to solve couple differential  equation with ode analyzer  but i get error

i want to plot y[1] and y[2]. 
for example for this two equation 
diff(y[1](x), x$2)+3*(diff(y[1](x), x$1))+2*y[1](x)+2*y[2](x) = 3, diff(y[2](x), x$2)+diff(y[2](x), x$1)+2*y[2](x)+2*y[1](x) = 8;
