(1/29)x+(4/145)y=1; (1/32)x+(9/320)y=1;解方程组,
(1/29)x+(4/145)y=1; (1/32)x+(9/320)y=1;
解方程组,
(1/29)x+(4/145)y=1; (1/32)x+(9/320)y=1;解方程组,
(1/29)x+(4/145)y=1两侧乘以290得 10x+8y=290 式(1)
(1/32)x+(9/320)y=1两侧乘以320得 10x+9y=320 式(2)
式(2)-式(1)得y=30
把y=30代入式(1)得 x=5
{3(x+y)+3(y+x)=1,3(x+y)+4(y-x)=-1
{3(x+y)-4(x-y)=4 {x+y/2 + x-y/6=1
(x+y)(x-y)+4(y-1)
x+y+2(-x-y+1)=3(1-y-x)-4-(y+x-1),x+y=?
已知x×x×y×y+x×x+y×y+1=4xy,求x,y的值快
已知:【(x²+y²)-(x-y)²+2y(x-y)】/4y=1,求4x/4x²-y²-1/2x+y
化简[(3x+4y)^2-(2x+y)(2x-y)+(-x+y)(5x-y)]除以-2y,其中x=-1,y=1
先化简 再求值 (2x-y)(y+x)-(x-2y)(2y+x)-(-3y+x)^2其(√x+1)+y^2+4=-4y
已知x-y=1,求[(x+2y)²+(2x+y)(x-4y)-3(x+y)(x-y)]÷y的值
已知x-y=1,求[(x+2y)^2+(2x+y)(x-4y)-3(x+y)(x-y)]除以y的值大神们帮帮忙
[(x+y)(x-y)-(x-y)^2-4xy]/2y,其中x=1,y=-1
[(y-2x)(-2x-y)-4(x-2y)²]*2y,其中x=1,y=2
[(y-2x)(-2x-y)+4(x-2y)平方]/3y,其中x=1,y=-3
[(2x+y)^2+(y+2x)(y-2x)-2y(4x-y)]/4y,其中x=1/2,y=1/3
先化简,再求值:[(x+y)(x-y)-(x-y)²+2y(x+y)]除4y,其中x=2,y=1
先化简,再求值:[(x+y)(x-y)-(x-y)^2+2y(x-3y)]/(-4y),其中x=1,y=-2
x²+xy/(x-4y)(x+y),其中x=4,y=-1
9y=3x-(x-1),4(x+y)-(2x+4)=8y
