數學問題 : 5y = 4y + y/3, y = ?

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

因為任何一個數字乘以0都會等於0, 所以y = 0。

數學問題 : 5y = 4y + y/3, y = ?
請問...

5y = 4y + y/3, y = ?

請提供步驟 + 答案.. 謝謝 =)



冇得計喔...



是否打錯????????????????




























1

5y=4/y+y/3
4/y=(5-1/3)y
y^2=4/(14/3)=6/7
y=0.926 or -0.926

sorry,答錯了,5y=4y+y/3
y=y/3
y=0

設Y=3。

5y = 4y y/3

5 x 3 = 4 x 3 3/3

15 = 12 1

15 = 13

= 2

Y = 2//

冇錯...

真係一定要計既話Y係可以等於0

但係你個心係咁諗既

你一世都係0


























.

5y = 4y + y/3

5y - 4y = 4y + y/3

y = y/3

5y = 4y + y/3
5y - 4y = 4y + y/3 - 4y
1y = y/3
y = y/3
