Use fsolve and a bit of algebra:
f = @(x,y) [y.^2 - x; 2.*y-x.^2 + 2];
XY0 = [1; 1];
XY = fsolve(@(b) f(b(1),b(2)), XY0);
There are several solutions. Experiment with ‘XY0’ to find all of them.

First you have to make a function like this in a certain directory
function F=eqn(k)
Name the function as eqn and save it
Then in that same directory(folder) run this coode from command window or a file if you want to.Make sure that the directory is same, If confused use
cd('----your folder path-------')
The code goes here
kl=[2;78] %imagine values of x and y to be any number
k=fsolve(@eqn,zg) %solve nonlinear function by this
x=k(1) %the first value returned is of x and the other of y as defined earlier in eqn function
