x=1,y=1.x=2,y=5.x=3,y=14.x=4,y=30.写出函数表达式,
x=1,y=1.x=2,y=5.x=3,y=14.x=4,y=30.写出函数表达式,
x=1,y=1.x=2,y=5.x=3,y=14.x=4,y=30.写出函数表达式,
y=x(x+1)(2x+1)/6
x-y/x-x+y/y-(x+y)(x-y)/y² y/x=2
若2/x-1/y=3,求[y/x-y/x-y(x-y/x-x+y)]/x-2y/x的值
(3x-y)^2+(3x+y)(3x-y),x=1,y=-2
二元一次方程 :2(x+y)-(x-y)=3 (x+y)-2(x-y)=1
2(x+y)-3(x-y)=1 6(x+y)+(x-y)=51
{3(x+y)-4(x-y)=4 {x+y/2 + x-y/6=1
变量x,y满足约束条件,x+y>=3,x-y>=-1,2x-y
(x-y)^2+(x+y)(x-y) 其中 X =3 Y=-1
(x-y)/(x+y)=3求( 3x-2y-1)/(x+y-5)
(x+y)(x-y)+(x-y)平方-(x-y)(3x-y) 其中x=-2 y=3分之一
(x-y) (x-2y)+(x+2y) (x-3y)-2(x-3y) (x-4y)=
已知x-y/x+y=3,求代数式5(x-y)/x+y-x+y/2(x-y)
{(x+y)/2+(x-y)/3=1,(x+y)-5(x-y)=2.求x=?,y=?
(x+y)(2x-3y)=?
x+y+2(-x-y+1)=3(1-y-x)-4-(y+x-1),x+y=?
化简 x / y(x+y) - y / x(x+y) =
[3x^2-(x+y)(y-x)][2(-x-y)(y-x)+2x^2+3y^2],其中x=-2分之1,y=1.5
已知:2x+y=6,x-3y=1 求7y(x-3y)(x-3y)-2(3y-x)(3y-x)
