Find all ordered pairs of real numbers (x,y) that satisfy x + y + sqrt(x + y) = 56 and x - y + sqrt(x - y) = 30.
I could find only one such pair !!.
a=1; b=-100;c=(a+b+sqrt(a+b);d=(a-b)+sqrt(a-b); if(c==56 and d==30, goto5, goto6);printa, b; a++;if(a<100, goto2, 0);a=1;b++;if(b<100, goto2, discard=0
a = 37 and b = 12
