已知x/4=y/5=z/6则(x+y)(y+z)=
已知x/4=y/5=z/6则(x+y)(y+z)=
已知x/4=y/5=z/6则(x+y)(y+z)=
楼主我告诉你个万能公式很适合这种题型的哦!
已知x/4=y/5=z/6则(x+y)(y+z)=
则:x=4k y=5k z=6k
然后把这些数据都带入(x+y)(y+z) 里去
最后把K约掉
就求出来了 应用题,和填空题都适用哦!
已知x/4=y/5=z/6则(x+y)(y+z)=
已知3X=4X,5Y=6Z求X+Y:Y+Z
已知x:4=y:5=z:6.则x:y:z= (x+y):(y+z)=
已知(x+2y)/3=(y+3z)/4=(z+5x)/5,则x:y:z=
已知x+2y/3=y+3z/4=z+5x/5,则x:y:z=?
已知x+2y/3=y+3z/4=z+5x/5,则x:y:z=
已知x+y=3,当y+z=4,x+z=5,则x+y+z等于()
已知2x+5y+4z=15.7x+y+3z=14 则x+y+z=?
已知x+4y-3z=0,4x-5y+2z=0,则x:y:z
已知x+4y=3z,4x-5y=-2z,则x:y:z
已知2x+5y+4z=6 3x+y-7z=-4求x+y-z
已知方程组4x-5y+2z=0 x+2y=3z 则x:y:z
已知x/4=y/5=z/6 求x+y+z/3x-2y+z的值
已知x/4=y/5=z/6,求x+y+z/3x-2y+z的值.
已知:4x-5y+2z=0 x+4y-3z=0则:(x*x+y*y+z*z)/(x*y+y*z+z*x)=____.
已知x:4=y:5=z:6,则1. x:y:z=? 2.(x+y):(y+z)
已知4x-3y-6z=0,x+2y-7z=0,则x-y+z/x+y+z=_________
已知4x-3y+6z=0 x+2y-7z=0 则x-y+z/x+y-z=?
