Answer:
There´s no solution to this system
Step-by-step explanation:
We have
[tex]x^2+y^2=1 \\x^2+y^2=4[/tex]
So by using any method we will eliminate both variables, for example by using elimination method.
We will multiply the first equation by (-)
so we have
[tex]-x^2-y^2=-1 \\x^2+y^2=4\\ 0=3[/tex]
Plotting the two equations we will have two circles so now its obvious that we don´t have any solution because we don´t have any intersection
