2Y-1/3-10Y+1/6=2Y+1/4-1求Y等于几2Y-1/3-10Y+1/6=2Y+1/4-1求Y等于几2Y-1/3-10Y+1/6=2Y+1/4-1求Y等于几(2Y-1)/3-(10Y+1)
2Y-1/3-10Y+1/6=2Y+1/4-1求Y等于几
2Y-1/3-10Y+1/6=2Y+1/4-1求Y等于几
2Y-1/3-10Y+1/6=2Y+1/4-1求Y等于几
(2Y-1)/3-(10Y+1)/6=(2Y+1)/4-1
4(2y-1)-2(10y+1)=3(2y+1)-12
8y-4-20y-2=6y+3-12
-12y-6y=-9+6
-18y=-3
y=1/6
2Y-1/3-10Y+1/6-2Y-1/4+1=0
10Y=7/12
Y=7/120
y (3y^2+8y-3)-6y(3y+2y-1)+9y
通分 y+3/y*y-6y+9,1/2y+6,y-1/y*y-9
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
