8y–3(3y+2)=6

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= 8y–3(3y+2)=6 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 1.5y+8y-6y=2y-3咋做? [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),'.') 6y-(y+2分之y+2-y分之y)÷(y^3-4y-2y^2+8分之y) 怎么算 2y+5/3y-6-y/2=5y-4/2y-4 -2y(y-3)=-3(6-2)y -2y(y-3)=-3(6-2)y -2y(y-3)=-3(6-2)y 12y(x-y)^2-8(x-y)^3=? 3Y-2=Y+1+6Y 3y+2=y-1+6y 不要分数 [2(x-y)^5-8(x-y)^2(x+y)+6y(x-y)^2]÷2(x-y)^2[2(x-y)^3-8(x-y)^2(x+y)+6y(x-y)^2]÷2(x-y)^2 y=(y')^3+y'
