{x+5y=18 5x-3y=14
x+5y=18
x=18-5y

90-28y=14
28y=76
y=19/7
x=18-95/7=31/7
x+5y=18 5x-3y=14
x=31/7 y=19/7
(x+y-5)*(x+y-5)+(x-y+3)=0 x*x-y*y
已知:3x-5y=0,求x/y,x-y/y,x-y/x
6(x-y)-2(x+y)=14 3(x-y)+(x+y)=5
已知x-y/x+y=3,求代数式5(x-y)/x+y-x+y/2(x-y)
(5x+3y)(3y-5x)-(4x-y)(4y+x)=
4(x-y)-3(x-y)=9 5(x-y)+2(x-y)=11
3(x+y)-4(x-y)=11,2(x-y)+5(x+y)=27
x+y/2+x-y/6=5 2(x+y)-3(x-y)=-2
3(x+y)+2(x-y)=36 4(x+y)-5(x-y)=2
(x-y)/(x+y)=3求( 3x-2y-1)/(x+y-5)
已知x/5=y/3,则(x/x+y)+(y/x-y)-(yxy/xxx-yxy)
先化简再求值(x-y)(x-2y)+(x-2y)(x-3y)-2(x-3y)(x-4y) x=4 y=5
{(x+y)/2+(x-y)/3=1,(x+y)-5(x-y)=2.求x=?,y=?
|x|=3 |y|=5 |x-y|=|x|+|y| 求 X+Y和 X-Y 等于多少
解方程组 (x+y)^2-3(x+y)=54 (x-y)^2-5(x-y)=14
(计算方程组x+y)/2=6-(x-y)/3,6(x+y)-5(x-y)=18
6 x+-18 y=14 -8 x+14 y=5 求x y
3y=18-5x 3x=4+5y 求x,y
