2(y-1)=2y-3(y+1)2(y-1)=2y-3(y+1)2(y-1)=2y-3(y+1)2y-2=2y-3y-32y-2y+3y=-3+23y=-1y=-1/3
2(y-1)=2y-3(y+1)
2(y-1)=2y-3(y+1)
2(y-1)=2y-3(y+1)
2y-2=2y-3y-3
2y-2y+3y=-3+2
3y=-1
y=-1/3
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
y (3y^2+8y-3)-6y(3y+2y-1)+9y
解方程：3y^2-(2y+1)(y-1)=(y-5)(y+1)
解方程3y^2-(2y+1)(y-2)=(y-5)(y-1)
2(y-4)(3y+2)-5(-3y+7)(y+1),其中y=-1
解方程：3y²-(2y+1)(y-2)=(y-5)(y+1)
(y-4)(3y+2)-(3y-7)(2y+1),其中y=4/3
解分式方程（y+3)/(y^2+y)-1/(1-y)=4/y要过程
Y(Y-1)-(y-2)*(y+3)=2 Y的解是多少?
方程y''=(1+y'*y')/2y的通解
y'=1+y^2
通分 y+3/y*y-6y+9,1/2y+6,y-1/y*y-9
y-(y-1)/2=1-(2y-3)/5
2(y-1)=2y-3(y+1)
解方程3y(y-1)=2(1-y)
y-y-1/2=3-y+2/5
