✔ 最佳答案
36 - 2.4Y = 15.6- 2.4Y= 15.6 - 36
- 2.4Y= -20.4
Y= -20.4/- 2.4
Y= 8.5
驗算：
36 - 2.4Y
= 36 - 2.4 ( 8.5)
= 36 - 20.4
= 15.6 ﹝和方程一開頭的 R.H.S. 一樣，因此答案正確。﹞

R.H.S. 即是 Right Hand Side ﹝右手面﹞的 簡寫。

36-2.4Y=15.6
2.4Y=36-15.6
2.4Y=20.4
Y=20.4/2.4
Y=8.5
2.4Y=36-15.6
2.4Y=20.4
Y=20.4/2.4

36-2.4Y+2.4Y=15.6+2.4Y
15.6+2.4Y=36
15.6+2.4Y-15.6=36-15.6
2.4Y=20.4
2.4Y/2.4=20.4/2.4
Y=8.5
15.6+2.4Y=36
15.6+2.4Y-15.6=36-15.6

36=15.6+2.4Y
15.6+2.4Y=36
2.4Y=36-15.6
Y= 20.4除以2.4
Y=答案啦(自己計)
15.6+2.4Y=36
2.4Y=36-15.6
Y= 20.4除以2.4

36 - 2.4Y = 15.6
36 - 2.4Y + 2.4Y = 15.6 + 2.4Y
15.6 + 2.4Y = 36
15.6 - 15.6 + 2.4Y = 36 - 15.6
2.4Y = 20.4
Y = 8.5
36 - 2.4Y + 2.4Y = 15.6 + 2.4Y
15.6 + 2.4Y = 36
15.6 - 15.6 + 2.4Y = 36 - 15.6
2.4Y = 20.4
Y = 8.5

36 - 2.4Y = 15.6
36 = 15.6 + 2.4Y
36 - 15.6 = 2.4Y
20.4 = 2.4Y
20.4 / 2.4 = Y
8.5 = Y
Y = 8.5
36 = 15.6 + 2.4Y
36 - 15.6 = 2.4Y
20.4 = 2.4Y
20.4 / 2.4 = Y
8.5 = Y
Y = 8.5

36 - 2.4Y = 15.6
36-2.4Y-36=15.6-36
-2.4Y=-20.4
(-2.4Y)/-2.4=(-20.4)/2.4
Y=8.5
36-2.4Y-36=15.6-36
-2.4Y=-20.4
(-2.4Y)/-2.4=(-20.4)/2.4
Y=8.5
