1.5y+8y-6y=2y-3咋做?1.5y+8y-6y=2y-3咋做?1.5y+8y-6y=2y-3咋做?移项、得1.5y=-3系数化为一、y=-2很简单的呀
1.5y+8y-6y=2y-3咋做?
1.5y+8y-6y=2y-3
咋做?
1.5y+8y-6y=2y-3咋做?
移项、得1.5y=-3
系数化为一、y=-2
很简单的呀
1.5y+8y-6y=2y-3咋做?
y (3y^2+8y-3)-6y(3y+2y-1)+9y
(y^2)^4y-(-2y)^3y^6=
【2(x-y)^3-8(x-y)^2(x+y)+6y(x-y)^2】/2(x-y)^2=
5x-3y=x+2y咋做?
啊啊啊啊!做题代数式9-6y-4y*y=7,则2y*y+3y+7的值是( )
y=(y')^3+y'
y-7-8y=2y-3-5y 咋写?
求方程 8y-3(3y-2)68y-3(3y-2)=6
解方程:(y+4)/5+y+6=(y+8)/2-(y+4)/3要过程
6y-(y+2分之y+2-y分之y)÷(y^3-4y-2y^2+8分之y) 怎么算
[T,Y]=ode45(@rigid,[0 1],[rand(15,1)]);plot(T,Y(:,1),'-',T,Y(:,2),'-.',T,Y(:,3),'.',T,Y(:,4),'-',T,Y(:,5),'-.',T,Y(:,6),'.',T,Y(:,7),'-',T,Y(:,8),'-.',T,Y(:,9),'.',T,Y(:,10),'-',T,Y(:,11),'-.',T,Y(:,12),'-.',T,Y(:,13),'.',T,Y(:,14),'-',T,Y(:,15),'.')
2y+5/3y-6-y/2=5y-4/2y-4
先化简,在求值:6y-(y+2分之y + 2-y分之y)除以y³-4y-2y²+8分之y,其中y= -2分之5先化简,在求值:6y-(y+2分之y + 2-y分之y)除以y³-4y-2y²+8分之y,其中y= -2分之5
方程怎么做:2y+3y=6解一下:2y+3y=6求你了
(x+y)(x-y)+3y^2怎么做?
y-1/2-y+1/3≥y怎么做
【2(x-y)(x-y)(x-y)-8(x-y)(x-y)(x+y)+6y(x-y)(x-y)]/2(x-y)(x-y)
