5x+2y=12,3x+2y=-6,求x= ,y=现在就要,快
5x+2y=12,3x+2y=-6,求x= ,y=
现在就要,快
5x+2y=12,3x+2y=-6,求x= ,y=现在就要,快
5x+2y=12,.(1)
3x+2y=-6 .(2)
(1)-(2):2x=18,x=9
5*9+2y=12,2y=-33,y=-33/2
x=9,y=-16.5
已知x-y/x+y=3,求代数式5(x-y)/x+y-x+y/2(x-y)
(x-y)/(x+y)=3求( 3x-2y-1)/(x+y-5)
6x+5Y=31 2X+3Y=17求X求 Y
x+y/2+ x-y/2=6 2(x+y)-3x+3y=24 求X Y
{(x+y)/2+(x-y)/3=1,(x+y)-5(x-y)=2.求x=?,y=?
6x-2y=5 8x-3y=-5 求x,y
如果|x+y+z-6|+|2x+3y-z-12|+|2x-y-z|=0求x,y,
已知:2x+y=6,x-3y=1 求7y(x-3y)(x-3y)-2(3y-x)(3y-x)
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
5X+Y=3 X+5Y=2 求x和y.5X+Y=3X+5Y=2求x和y.
已知x-y=3,求[(x+y)(x-y)-(x-y)^2+2y(x-y)]除以的值
已知3x =2y 求x/x+y+y/x-y-y²/x²-y²
已知:3x-5y=0,求x/y,x-y/y,x-y/x
若2/x-1/y=3,求[y/x-y/x-y(x-y/x-x+y)]/x-2y/x的值
已知|x|=2,|y|=3,|x+y|=-(x+y)求x-y
求(X+Y)(X-Y)(X²+Y²),X=5 Y=2,
y=3(x-y),x=2(x-y)求x,y的值
