数学问题 : 5y = 4y + y/3, y = ?

Answer 1

更新1:

我想 y = ?..最后的答案应该是没有未有未知数的!!

5y = 4y + y/3 5y - 4y = 4y + y/3 - 4y y = y/3 y - y/3 = y/3 -y/3 2y/3 = 0 y = 0 因为任何一个数字乘以0都会等于0
所以y = 0。

5y=4/y+y/3 4/y=(5-1/3)y y^2=4/(14/3)=6/7 y=0.926 or -0.926 2008-04-01 15:33:31 补充： sorry
答错了
5y=4y+y/3 y=y/3 y=0
设Y=3。 5y = 4y y/3 5 x 3 = 4 x 3 3/3 15 = 12 1 15 = 13 = 2 Y = 2 2008-04-06 12:12:00 补充： 冇错... 真系一定要计既话Y系可以等于0 但系你个心系咁谂既 你一世都系0 .

网友加自己
5y = 4y + y/3 5y - 4y = 4y + y/3 y = y/3
参考: me
5y = 4y + y/3 5y - 4y = 4y + y/3 - 4y 1y = y/3 y = y/3
