✔ 最佳答案
5y = 4y + y/35y - 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。

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

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