(2x-4y-6)2=-|3x+2y-17|则x=——,y=——(2x-4y-6)2=-|3x+2y-17|则x=——,y=——(2x-4y-6)2=-|3x+2y-17|则x=——,y=——(2x-
(2x-4y-6)2=-|3x+2y-17|则x=——,y=——
(2x-4y-6)2=-|3x+2y-17|则x=——,y=——
(2x-4y-6)2=-|3x+2y-17|则x=——,y=——
(2x-4y-6)²=-|3x+2y-17|
那么(2x-4y-6)²+|3x+2y-17|=0
所以2x-4y-6=0,3x+2y-17=0
解方程组得x=5,y=1
如果不懂,祝学习愉快!
{3(x+y)-4(x-y)=4 {x+y/2 + x-y/6=1
解二元一次方程组:3(x+y)-4(x-y)=4,x+y/2+x-y/6+1x+y/2+x-y/6+1=1
(x+y)/2- x-y/2=6 3(x+y)=4(x-y)
x+y/3+x-y/2=6 4(x+y)-2(x-y)=40
x+y/2+x-y/3=6,4(x+y)-3(x-y)=-20
{(x+y)/2+(x-y)/3=6 4(x+y)-3(x-y)=-20
4(x+y)-3(x-y)=-20,2/x+y+3/x-y=6
2(x+y)-3(x-y)=1 6(x+y)+(x-y)=51
x+y+2(-x-y+1)=3(1-y-x)-4-(y+x-1),x+y=?
{x+y=1 ,xy=-6{x(2x-3)=0,y=x²-1{(3x+4y-3)(3x+4y+3)=0,3x+2y=5{(x-y+2)(x+y)=0,x²+y²=8{(x+y)((x+y-1)=0,(x-y)(x-y-1)=0
(x-y) (x-2y)+(x+2y) (x-3y)-2(x-3y) (x-4y)=
先化简 再求值 (2x-y)(y+x)-(x-2y)(2y+x)-(-3y+x)^2其(√x+1)+y^2+4=-4y
化简[(3x+4y)^2-(2x+y)(2x-y)+(-x+y)(5x-y)]除以-2y,其中x=-1,y=1
已知:2x+y=6,x-3y=1 求7y(x-3y)(x-3y)-2(3y-x)(3y-x)
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
2(x-y)/3-(x+y)/4=-1 (1) 6(x+y)-4(2x-y)=16 (2)
(2x-2y)/3-(x-y)=-1和6(x+y)-4(2x-y)=16
