3x-2y=7 2/3(x-1)-4y=8 求x和y3x-2y=7 2/3(x-1)-4y=8 求x和y
不对,算错了
{3(x+y)-4(x-y)=4 {x+y/2 + x-y/6=1
(x-y) (x-2y)+(x+2y) (x-3y)-2(x-3y) (x-4y)=
x+y+2(-x-y+1)=3(1-y-x)-4-(y+x-1),x+y=?
已知:2x+y=6,x-3y=1 求7y(x-3y)(x-3y)-2(3y-x)(3y-x)
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)]除以y的值大神们帮帮忙
已知x-y=1,求[(x+2y)²+(2x+y)(x-4y)-3(x+y)(x-y)]÷y的值
初二上学期方程题 4x+y=5 5x+4y=63x-2y=1 2x+3y=13x-2y=7 7x+5y=32x+3y=17 2x-y=-4x+5y=6 2x+y=23x-6y=4 3x+2y=52x+y=73x-4y=53x+y=1x-2y=-1x+y=42x+3y=92x-3y=74x+5y=3x+y=20004x+6y=90003x+5y=113x-2y=42x+3y=215x-2y=5x+y=54x+3y=182x+3y=16x+4y=132x+3y=40x
已知X和Y满足3X+4Y=2,X-Y-1/7
[(y-2x)(-2x-y)+4(x-2y)平方]/3y,其中x=1,y=-3
若2/x-1/y=3,求[y/x-y/x-y(x-y/x-x+y)]/x-2y/x的值
[(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-3y)]/(-4y),其中x=1,y=-2
9y=3x-(x-1),4(x+y)-(2x+4)=8y
已知(x+y)2 =2,(x-y)3 =3,求(x+y)7(x-y)2(x+y)3(y-x)4 的值
x+y=1 5x-2y=8 3x-y=7 2x-y=3x表示y和用y表示x
为什么(x-2y)(x+4y)-(x-2y)+3(x+4y)-3=(x-2y+3)(x+4y-1).
