Answer:
x +y =24
Step-by-step explanation:
(x - 8) 2 + (y + 2) 2 = 64
2x - 16 +2y+4 =64
2x + 2y =64-16
2x+2y = 48
divide both side with 2 we get
2x/2 +2y/2 =48/2
simplify
x + y =24
hence equation is x +y =24
Answer:
xy=32
Step-by-step explanation:
(2x - 16) + (2y + 4) = 64
(4xy - 64)=64
+64 +64
4xy = 128
4xy/4 = 128/4
xy = 32
