4(2y+5)-3y=7(y-5)+4(2y+1)
3(x+2)- 4(x-1)+2(3x-1)=18
7(3-x)+2(x-5)+3(x-1)+8=0
4(2y+5)-3y=7(y-5)+4(2y+1)3(x+2)- 4(x-1)+2(3x-1)=187(3-x)+2(x-5)+3(x-1)+8=0
2(y-4)(3y+2)-5(-3y+7)(y+1),其中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
2y+5/3y-6-y/2=5y-4/2y-4
4(2y+5)-3y=7(y-5)+4(2y+1)
3-5-2y/5=y-4-7y/10+y+2/2
10y-2(7y-2)=5(4y+5)-3y
4(5—2y)+7(y+1)=3(4y-1)+17求y
4*(5—2y)+7(y+1)=3(4y-1)+17求y
10y+2(7y-2)=5(4y+3)+3y怎么算

3(y-2)=4y-5
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!
(2y+5/3y)²-5y×(5/3y+y)=4 求y的值.(2y+5/3y)的平方-5y×(5/3y+y)=4
已知(3x+1)(3x-3)-3x+2)^2=-7,(y+7)(y-7)-y(y-7)=0,求8y^2-5y(-y+3x)+4y(-4y-5/2x)的值
(-y+5+4y^2)-(-y^2+5y-4),其中y=-2
(y-4)(3y+2)-(3y-7)(2y+1),其中y=4/3
解3y+5/3y-6=1/2+5y-4/2y-4
