x=(y-1)/(y+1)x(y+1)=y-1xy+x=y-1xy-y=-x-1(x-1)y=-(x+1)y=-(x+1)/(x-1)
约掉y结果32.4再问:看补充问题再答:y不存在无解
原式=1/2x-[1/(x+y)][(x+y)/2x-(x+y)]=1/2x-[1/(x+y)](x+y)(1/2x-1)=1/2x-(1/2x-1)=1/2x-1/2x+1=1
1元=1Y币
Y电流没听说过,不过安(A)与毫安(mA)之间的转换关系是一千倍——1A=1000mA.
2:1貌似

题在哪
是1/x+1/y=5么?题不对吧
∵4y²-2y+5=74y²-2y=7-54y²-2y=2∴2y²-y=1那么1-2y²+y=1-(2y²-y)=1-1=0
让我来,张浩然,不必谢啦有``
y=lg2x=lg2+lgxdy=1/[(1n10)x]dx
|2x-y+1|+(x+2y-7)的平方等于0则有2x-y+1=0--->2x-y=-1x+2y-7=0--->x+2y=7两式相加得3x+y=6与2x-y=-1相加得5x=5x=1y=3所以(x+y
8y-9y=-y
答:∫1/(y-y^2)dy=∫{1/[y(1-y)]}dy=∫[1/y+1/(1-y)]dy=∫1/ydy+∫1/(1-y)dy=In│y│-In│1-y│+C=In│y/(1-y)│+CC为常数.
10个Y点
Y点是歪歪个人用户充值后的支付货币,可用来购买Y点类的商品.1元(RMB)=10Y点可以点击支付后获得
(5y+1)÷6=(9y+1)÷8-(1-y)÷3[(5y+1)÷6]×24=[(9y+1)÷8-(1-y)÷3]×244×(5y+1)=3×(9y+1)-8×(1-y)20y+4=27y+3-8+8
