10y+7=22y-5-3y y=?
10y+7=22y-5-3y y=?
10y+7=22y-5-3y y=?
10y+7=22y-5-3y
移项
22y-10y-3y=7+5
9y=12
y=4/3
10y+7=22y-5-3y
移项
22y-10y-3y=7+5
9y=12
y=4/3
10y+7=22y-5-3y
10y+7=19y-5
9y=12
y=4/3
10Y+7=22Y-5-3Y
10Y+7=19Y-5
19Y-5=10Y+7
19Y-10Y=12
9Y=12
Y=12/9
Y=4/3
10y+7=22y-5-3y
10y+7=19y-5
方程两边加5
10y+12=19y
方程两边减10y
9y=12
方程两边除以9
y=12/9=4/3
10y+7=19y-5
12=9y
y=4/3
10y+7=22y-5-3y 10y+7=22y-5-3y
10y+7=22y-5-3y y=?
10y+7=22y-11-3y
y=(y')^3+y'
2(y-4)(3y+2)-5(-3y+7)(y+1),其中y=-1
10y+2=22y-5-3y,Y等于几,解一元一次方程
10y-2(7y-2)=5(4y+5)-3y
3-5-2y/5=y-4-7y/10+y+2/2
10y+2(7y-2)=5(4y+3)+3y怎么算
[T,Y]=ode45(@rigid,[0 1],[rand(15,1)]);plot(T,Y(:,1),'-',T,Y(:,2),'-.',T,Y(:,3),'.',T,Y(:,4),'-',T,Y(:,5),'-.',T,Y(:,6),'.',T,Y(:,7),'-',T,Y(:,8),'-.',T,Y(:,9),'.',T,Y(:,10),'-',T,Y(:,11),'-.',T,Y(:,12),'-.',T,Y(:,13),'.',T,Y(:,14),'-',T,Y(:,15),'.')
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
7y-10y+5=4y-5
1.5(x+y)+3(x-y)=27(x+y)-3(x-y)=-62.x-y/7 - x+y/10 =1/22(x-y)-5(x+y)=3所谓细节决定成败,
3(y-3)-5(1+y)=7(y-1)
5(y-2)-7(y+3)=11(y+4)
(2y-3)(-y+4)=(y-2)(y-5)-3y(y-7/3)解方程
