(1)0.5y+1.1=4.5-1.2y (2)3(x+2)-2(x-2分之3)=5-4x
(1)0.5y+1.1=4.5-1.2y (2)3(x+2)-2(x-2分之3)=5-4x
(1)0.5y+1.1=4.5-1.2y (2)3(x+2)-2(x-2分之3)=5-4x
(1)0.5y+1.1=4.5-1.2y
1.7y=3.4
y=2
3(x+2)-2(x-2分之3)=5-4x
3x+6-2x+3=5-4x
5x=-4
x=-4分之5
1x=0.5y 2x=2y 3x=4.5y 求规律.(如y=...)如果y是1.5,x是多少?
方程y''=(1+y'*y')/2y的通解
微分方程y'-y=1
for(y=1;y
y'=1+y^2
for (y=1;y
y+y=1/cosx
y'/y=1/x
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
如何解带分母的二元一次方程组?1.x-1/0.5+y-1/0.2=2 1.2(x-y)/3-x+y/4=-12.x+y=2 2.6(x+y)-4(2x-y)=16
(x+y+z)÷10=x+1.1 y+x=z-80+y-1 z-y=8x+y+8 x+z÷y=?
已知y=-2,求2y-2/y^2-2y+1+y+1/y-1-y的值
方程y''-4y'+13y=0的通解方程y''=(1+y'*y')/2y的通解
(y-2)(y^2-6y-9)-y(y^2-2y-15),其中y=1/2.先化简再求值.
-y - y/1-y +1
y=(y')^3+y'
