Squaring First equ both side (Under root x+y)^2=7^2 then we get x+y=49 then y=49-x -----Equ. No.----(3) Squaring Second equ both side ^2=11^2 we get x^2+y=121 putting the value y from (3) equ. X^2+(49-X)=121 after solving we get X^2-X+49-121=0 then X^2-X-72=0 Using factorization splitting...

from the , you have x+Y=49,and from the second, you have root y=11-x, which gives y=(11-x)suare. put this y in x+y=49. then you will get a quadratic equatn of x. solve it and get the answer

Since we have ?x and a y in one equation and ?y and a x in the other, x and y must be positive(because u cannot hav a negative value inside the Sq Root), Since ?x + y = 7, then y ? 7 Since x + ?y = 11, then x ? 11 Assuming x and y are perfect squares(because u cannot hav a negative value inside...
