9(Y+6)=216
9y+54=216
9y=162
y=18
28-T=13
28-13=T
T=15

9(Y+6)=216
9(Y+6)/9=216/9
Y+6=24
Y+6-6=24-6
Y=18

28-T=13
28-T+T=13+T
28=13+T
28-13=13+T-13
15=T
T=15

9(Y+6) = 216
9Y+54 = 216
9Y = 216-54
9Y = 162
9Y/9 = 162/9
Y= 18

28-T = 13
28-13 = T
T = 15

1.9(Y+6)=216
9Y+54=216
9Y=216-54
9Y=162
Y=18

2.28-T=13
T=28-13
T=15

不是抄襲!!!!!

9(y+6)=216
即係9x(y+6)=216
將9x(y+6)抵消,即是9x(y+6)除9=216除9
y+6-6=24-6
y=18
答案即是18

28-t=13
要抵消：即是28-t+28=13+28
t=41
答覆就是41

28-T=13
28-t+t=13+t
28=13+t
28-13=13+t-t
15=t

I think this is right@

9(Y+6)=216
9Y+54=216
9Y=162
Y=18


28-T=13
28-13=T
T=15
