8y-3=5y+3
8y-3=5y+3
8y-3=5y+3
8y-5y=3+3
3y=6
y=2

y=(y')^3+y'
8y-3=5y+3
8=3-5y,求y
y(y-2)²-y(y+3)(y-5) y=1/2 化简求值
y(y-2)²-y(y+3)(y-5) y=1/2 化简求值
y(y-2)²-y(y+3)(y-5) y=1/2 化简求值
解方程:(y+4)/5+y+6=(y+8)/2-(y+4)/3要过程
y-7-8y=2y-3-5y 咋写?
3y-2(10-y)=4y-5(8-y)
[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),'.')
(4x-2y-z)-{5x[8y-2y-(x+y)]-x+(3y-10z)]=? kuaihuajian
(x+y)/y=8/3则x/y=__ y/x-y=___
(x+y)/y=8/3则x/y=__ y/x-y=___
2(y-4)(3y+2)-5(-3y+7)(y+1),其中y=-1
(x+y-5)*(x+y-5)+(x-y+3)=0 x*x-y*y
2y+5/3y-6-y/2=5y-4/2y-4
解方程3y^2-(2y+1)(y-2)=(y-5)(y-1)
解方程:3y^2-(2y+1)(y-1)=(y-5)(y+1)
