(4y-3)(3y-1)=4

(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 解分式方程（y+3)/(y^2+y)-1/(1-y)=4/y要过程 （y+3/y方+y）-（1/1-y）=4/y y方+y分之y+3-1-y分之1=y分之4很急, (y^2)^4y-(-2y)^3y^6= (y+3)(4y-1) 4y的平方-3y-1=y-2 3^(y+1)=4^y 求y 数学题=y(y+3)-4(y+3)2=(y+3)(y-4y-12) calculus,y''+4y'+3y=0,y(0)=0,y'(0)=1,y=? y-1/y-2 - y-3/y-4=y-2/y-3 - y-4/y-5一共有四个分数哦~希望可以快一点~谢谢! y(y+4)-y(y-3)-9y详细解答 常微分方程的通解dy/dx=(x-y+1)/(x+y-3)y^4=2y^n+y=0y''+6y'+9y=e^(-3x)y''+y'-2y=4e^(2x) {3(x+y)+3(y+x)=1,3(x+y)+4(y-x)=-1 y^+3y-1=0,求y^4/^8-3y^4+1的值 解3y+5/3y-6=1/2+5y-4/2y-4 4Y^3+3Y^2+4Y+1=0求Y
