Rewrite the formula so you get y as a function of x. Then you can get random x values and get the corresponding y values.

If you have symbolic toolbox:
syms x y
eqn = x.^2+(3/2*y-sqrt(abs(x)))^2 == 3;
z(x) = solve(eqn,y);
xrand = rand(1,100); %Some random numbers
yrand = cell2mat(cellfun(@double,z(xrand),'UniformOutput',false));
