Hello student, please check the solution of your question given below
x^2+y^2+2xy=13+2*6
(x+y)^2=25
x+y=5.......................1
x^2+y^2-2xy=13-2*6
(x-y)^2=1
x-y=1..............................2
solving equation 1 & 2
we get x=3 & y=2
x^2+y^2+2xy=13+2*6
(x+y)^2=25
x+y=5.......................1
x^2+y^2-2xy=13-2*6
(x-y)^2=1
x-y=1..............................2
solving equation 1 & 2
we get x=3 & y=2
