x+2y=10 3x—2y=6 解得:x=___,y=___ ,
x+2y=10 3x+2y=6 解得:x=___,y=___ 要,
由X/Y=2Y/X-Y 怎么解得x=2y?
解关于x,y的方程组3x+y=10m,3x-2y=7m得?
解方程组 10(x-y)=3(x+y)+15 6(x+y)=4(2x-y)+1610(x-y)=3(x+y)+156(x+y)=4(2x-y)+16
解方程组 10(x-y)=3(x+y)+15 6(x+y)=4(2x-y)+1610(x-y)=3(x+y)+156(x+y)=4(2x-y)+16分开的。
3(x+y)—4(x-y)=4,(x+y/2)+(x-y/6)=1.解方程组
x-y/x-x+y/y-(x+y)(x-y)/y² y/x=2
数学题(2x+y):(x+2y)=2:3,x:y得多少
解方程组,x+y/2=3x-2y=10+6x+y/4,
【2(x-y)^3-8(x-y)^2(x+y)+6y(x-y)^2】/2(x-y)^2=
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/6=5 2(x+y)-3(x-y)=-2
(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
