Answer 2

32/(x + y) + 16/(x - y) = 8

y = 1 - sqrt(x^2 - 6 x + 1), sqrt(x^2 - 6 x + 1) + x - 1!=0

y = sqrt(x^2 - 6 x + 1) + 1, -sqrt(x^2 - 6 x + 1) + x - 1!=0

x = 3 - 2 sqrt(2), y = 1

x = 3 + 2 sqrt(2), y = 1

Answer 3

32÷(x+y)+16÷(x－y)=8
解: 32/(x+y）+16/(x－y)=8
4/(x+y)+2/(x－y)=1
4(x－y)+2(x+y)=(x²－y²)
4x－4y+2x+2y=x²－y²
6x－2y=x²－y²
x²－6x－y²+2y=0
(x²－y²)－2(3x－y）=0

Answer 4

方程为32÷(x+y)+16÷(x-y)=8，4÷(x+y)+2÷(x-y)=1，6÷(x-y)=1，得:x-y=6
