5(y-2)-7(y+3)=11(y+4)
y=(y')^3+y'
1.4(x-y-1)=3(1-y)-22/x+3/y=22.5(x+y)-6=43x+3y+7y=10
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,
10y+2=22y-5-3y,Y等于几,解一元一次方程
解方程:4y-3(20-y)=6y-7(11-y)
4y-3(20-y)=6y-7(11-y)
解方程4y-3(20-y)=6y-7(11-y)求过程
4y-3(20-y)=6y-7(11-y) 解方程
10y+2(7y-2)=5(4y+3)+3y怎么算
10y-2(7y-2)=5(4y+5)-3y
3-5-2y/5=y-4-7y/10+y+2/2
(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
