X+y=960x/y=5/3X+y=960x/y=5/3X+y=960x/y=5/3由x/y=5/3得y=3x/5代入x+y=960x+3x/5=9608x/5=960所以x=600y=3x/5=36
X+y=960 x/y=5/3
X+y=960 x/y=5/3
X+y=960 x/y=5/3
由x/y=5/3得y=3x/5
代入x+y=960
x+3x/5=960
8x/5=960
所以
x=600
y=3x/5=360
x+y=960..............(1) x/y=5/3..............(2)
由(2)可得y=3/5x.....................(3)
把(3)带入(1)中有 x+3/5x=960
得x=600
y=360
(x+y-5)*(x+y-5)+(x-y+3)=0 x*x-y*y
已知:3x-5y=0,求x/y,x-y/y,x-y/x
已知x-y/x+y=3,求代数式5(x-y)/x+y-x+y/2(x-y)
X+y=960 x/y=3/5
X+y=960 x/y=5/3
(5x+3y)(3y-5x)-(4x-y)(4y+x)=
4(x-y)-3(x-y)=9 5(x-y)+2(x-y)=11
3(x+y)-4(x-y)=11,2(x-y)+5(x+y)=27
x+y/2+x-y/6=5 2(x+y)-3(x-y)=-2
6(x-y)-2(x+y)=14 3(x-y)+(x+y)=5
3(x+y)+2(x-y)=36 4(x+y)-5(x-y)=2
(x-y)/(x+y)=3求( 3x-2y-1)/(x+y-5)
已知x/5=y/3,则(x/x+y)+(y/x-y)-(yxy/xxx-yxy)
先化简再求值(x-y)(x-2y)+(x-2y)(x-3y)-2(x-3y)(x-4y) x=4 y=5
{(x+y)/2+(x-y)/3=1,(x+y)-5(x-y)=2.求x=?,y=?
|x|=3 |y|=5 |x-y|=|x|+|y| 求 X+Y和 X-Y 等于多少
推倒公式:(x+y)(x*x-3x+y*y)=x*x*x+y*y*y怎么做.
化简[(3x+4y)^2-(2x+y)(2x-y)+(-x+y)(5x-y)]除以-2y,其中x=-1,y=1
