若x+y-8x-10y+41=0,求x／y+y／x的值

若x+y-8x-10y+41=0,求x／y+y／x的值 X+Y-8X+10Y+41=O,求X/Y-Y/X的值 x^2+y^2-8x+10y+41=0求(x+y)^2013 已知x²+y²-8x-10y+41=0,求x/y-y/x的值 x²+y²-8x-10y+41=0,求x/y-y/x的值. (x+y)(x+y-10)+25=0,且x-y=3,求x,y (x+y)(x+y-10)+25=0,且x-y=3,求x,y 已知:3x-5y=0,求x/y,x-y/y,x-y/x 若x²+2x+y²-6y+10=0求x y 若x,y为正数,且2*x+8*y-x*y=0,求x+y的最小值 若x*x+y*y-8x+6y+25=0,求y的x次方 若x^2+y^2-10x-6y+34=0,求（x-y)/(x+y)的值 已知X*X+Y*Y+6X-8Y+25=0 求（Y/X)+(X/Y)-2=? x*x+2x-y*y+6y-8=0,x+y不等于2,求x-y的值 若(x*x+y*y)(x*x+y*y)-4x*x*y*y=0,求代数式(x*x+5xy+y*y)/(x*x+2xy+y*y)的值 求一道数学题解!已知：x²+y²-8x-10y+41=0,求x/y-y/x=? x的平方+y的平方—8x—10y+41=0,求x,y的值. 若x-y不等于0,2x-3y=0,则分式(10x-11y)/(x-y)的值是（）?(10x-11y)/(x-y) =[(8x-8y)+(2x-3y)]/(x-y) =8为什么8X-8Y=8？(10x-11y)/(x-y)=[(8x-8y)+(2x-3y)]/(x-y)=8+(2x-3y)]/(x-y)=8+0=8
