I want to simulate equations of first order differential equation. Can you please suggest me how to use simulink for first order differential equation simulation?

Equations are as follow x1'=y*x1 -x2+ l1*x1(x1^2+x2^2) x2'=x1+y*x2+l1*x2(x1^2+x2^2) y'=e data are: l1 =1 e=0.01 x1(0)=0.3 x2(0)=0.3 y(0)= -0.5
