y (3y^2+8y-3)-6y(3y+2y-1)+9y
(y+1)分之(2y+3)=(3y+4)分之(6y+7)
(y-4)(3y+2)-(3y-7)(2y+1),其中y=4/3
2(y-4)(3y+2)-5(-3y+7)(y+1),其中y=-1
(y+3/y方+y)-(1/1-y)=4/y
解不等式组2y+3小于9-y,6y-1<5,3y+7≥2-y
已知7/3*根号(9y)-y-2y*1/y=-2,求y的值
3(y-3)-5(1+y)=7(y-1)
3y(y-1)等于2(y-1)
(y+3)(4y-1)
通分 y+3/y*y-6y+9,1/2y+6,y-1/y*y-9
y(x+y)+(x-y)²-(x+y)(x-y),其中x=-1/3,y=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
解不等式y+3(y-1)
5(x-y)³-3(x-y)²+7(x-y)-5(x-y)³+(x-y)²-5(x-y),其中,x-y=1/3.5(x-y)³-3(x-y)²+7(x-y)-5(x-y)³+(x-y)²-5(x-y),其中,x-y=1/3先化简,再求值;
1/3(3y-10-7y/2)-1/2(2y-2y+2/3)=y/2-1 求y=( )/是分数线
