0.33(9y-3)+2(y+1)
0.33(9y-3)+2(y+1)
0.33(9y-3)+2(y+1)
请问你要化简吗.
0.33(9y-3)+2(y+1)
解(y-3分之2y+y+3分之y)×y分之y²-9
y (3y^2+8y-3)-6y(3y+2y-1)+9y
已知7/3*根号(9y)-y-2y*1/y=-2,求y的值
3y(y-1)等于2(y-1)
通分 y+3/y*y-6y+9,1/2y+6,y-1/y*y-9
计算:3y(y-4)(2y+1)-(2y-3)(4y²+6y-9)
3/1(9y-3)+2(y+1)
已知x-y=1,y≠0,求{(x+2y)²+(2x+y)(x+4y)-3(x+y)(x-y)}÷y的值.
三分之一(9y-3)+2(y+1)
三分之一(9y-3)+2(y+1)
1、求下列微分方程的通解:(1)2y‘’+y‘-y=2ex (2)2y‘’+5y‘=5x2-2x-1 (3)y‘’-6y‘+9y=e3x(x+
解方程(y-3)^3-(y+3)^3=9y(1-2y)
化简:(x+y)+(2x+y/1*2)+(3x+y/2*3)+...+(9x+y/8*9)
2(y-2)-9(1-y)=3(4y-1)y=-10. 对么
方程5y(2y-3)=(y+2)(y-2)-1
(2y+1)(3y-1)+(2-y)(6y-1)
3(Y+1)^2-5(Y+1)(Y-1)+2(Y-1)^2,化简
