解方程x+y=15 x/y=15/10x+y=15 x/y=15/10
{x/60+y/80=10,x/60+y/40=15、{2x/3+3y/4=1/5,5x/6-5y/2=2、{5/2(x+y)=1200,10/3(x+y)=1200{4x+5y=98,5y-4x=2、{x/3+y/4=54/60,y/4+x/5=42/60怎么解?{40-y=x-4 40-y=y-x
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。
10/x+y+3/x-y=-5 15/x+y-2/x-y=-1(用换元法解此方程组)
解分式方程:10/(x+y)+3/(x-y)=-5,15/(x+y)-2/(x-y)=-1
3/(X-Y)+10/(X+Y)=-5 2/(X-Y)-15/(X+Y)=1 解分式方程组
|x|+x+y=10,|y|+x-y=15,求x+y的值.帮帮我,谢谢!
解方程组x+y=15 (x+15%x+y+10%y)=17
求解二元一次方程 x+y=17 x-15%x+(y-10%y)=15
x+y/10+x/15=1x+y/12+y/15=1
已知x²+xy=10,y(x+y)=15,则x+y=
x=+15,y=-10,求x+y,x-y的补码需要过程
x+y+z=15 x+5y+10z=70 x,y,z,各是几?
x+y+z=15 x+5y+10z=70 x,y,z,各是几?
