second-degree linear system

I want to solve a second-degree linear system, but I can not find anything. Want to resolve a system like this: {x^(2)−xy = y^(2)+1 ; 12x+4+y=0 is there any Matlab function that solves this type of system? I could have an example of a code?

Answer 1

[KALYAN ACHARJYA]

syms x y 
[solx,soly]=solve(x^2-x*y-y^2-1==0, 12*x+4+y==0)

Answer 2

[ANKUR KUMAR]

ly make all equation equal to 0. Write this in a function and save this as as first.m

function F = first(x)
F(1)=(x(1)^2)-(x(1)*x(2))-(x(2)^2)-1;
F(2)=12*x(1)+4+x(2);
end

Now type this in command window

fun = @first;
x0 = [0,0];
x = fsolve(fun,x0)

Type this to get the iterated result.

options = optimoptions('fsolve','Display','iter');
[x,fval] = fsolve(@first,x0,options)
