|x-1|+|y-2|=6,|x-1|=2y-4,求x,y的值
|x-1|+|y-2|=6,|x-1|=2y-4,求x,y的值
|x-1|+|y-2|=6,|x-1|=2y-4,求x,y的值
∵|x-1|=2y-4≥0,
∴则y-2≥0
∵|x-1|+|y-2|=6
∴2y-4+y-2=6,得y=4
∵|x-1|=2y-4
∴x-1=±4,得x=-3或5
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
{6(x-y)-7(x+y)=21 {2(x-y)-5(x+y)=-1
已知:2x+y=6,x-3y=1 求7y(x-3y)(x-3y)-2(3y-x)(3y-x)
1.(x-2y)(x+2y)-(x平方+y)(x平方-y) 2.(2x-y)(y+2x)-(2y+x)(2y-x)3.已知:x+y=6,x平方-y平方=48,求x,y的值4.x平方-2x分之x+2 -- x平方-4x+4分之x-1
求值域 1,y=(x+2)/(x*x+3x+6) 2,y=3x/(x*x+4)
若2x-3y+4=0则x(x*x-1)+x(5-x*x)-6y+7
(x-2y)(x+y)-2x(-2x-3y)+6x(-x-y),其中x=-1,y=2
(x-2y)(x+y)-2x(-2x-3y)+6x(-x-y),其中x=-1,y=2要讲解和答题
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
已知x+y=a,2x-y=-2a,求[(x/y-y/x)/(x+y)-x(1/x-1/y)]/[(x+1)/y]的值
若2/x-1/y=3,求[y/x-y/x-y(x-y/x-x+y)]/x-2y/x的值
{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
