(3)(5y+4/3)+(y-1/4) =2-(5-3y/6)
(3)(5y+4/3)+(y-1/4) =2-(5-3y/6)
(3)(5y+4/3)+(y-1/4) =2-(5-3y/6)
5y+4/3+y-1/4-2+5-y/2=0
11y/2=-49/12
y=-49/66
(y+3/y方+y)-(1/1-y)=4/y
(96/y²16)+(3y-1/4-y)=(2y-1/y+4)-5
(2y+5/3y)²-5y×(5/3y+y)=4 求y的值.(2y+5/3y)的平方-5y×(5/3y+y)=4
计算:(1)8x^2y^2*(-3x/4y^5) (2)(x+y)^2/xy-y^2*(y-x)^2/xy+y^2
(y-3)/(4y-8)÷(y+2-5/(y-2))
因式分解、速~(y+3)*(y+5)*(y-4)*(y-6)+80=?
(x-y)^3×(y-x)^4+(x-y)^2×(y-x)^5
(y+1)分之(2y+3)=(3y+4)分之(6y+7)
3(y+1)>4y+2 2(y-1)≤3y 解不等式
4y(3y-2)-2y(6y+5)>8解不等式
(x+y)^6/(x+y)^4-(x-y)^5/(x-y)^3 化简 ..
[(x+y)(x-y)-(x-y)的平方+2y(x-y)]除以(4y)请帮我一下写两道计算题[(x+y)(x-y)-(x-y)的平方+2y(x-y)]除以(4y)[(3x+2y)(3x-2y)-(x+2y)(5x-2y)]除以(4x)
2(y-4)(3y+2)-5(-3y+7)(y+1),其中y=-1
-y³+4y²-4y;2x²-4xy;x²(y²-1)+(1-y²);1/5(x-y)+5(y-x)y²过程,方法教一下,3Q啦、
(5Y+4)/3+(Y-1)/4=2-(5Y-5)/12 Y=?
解方程3y+1/y+2+2/2-y=3-(3y/y的平方-4)
x²-y²+5x+3y+4(x+y-2xy)(x+y-z)+(xy-1)²
4(2y+3)=8(1-y)-5(y-2)解方程
