✔ 最佳答案
(1)8y - 34 = 2y - 10
8y - 2y = 34 - 10
6y = 24
y = 24 ÷ 6
y = 4
(2)
y + 2 = 3(4-y)
y + 2 = 3×4 - 3y
y + 2 = 12 - 3y
y + 3y = 12 - 2
4y = 10
y = 10 ÷ 4
y = 2.5
參考: 有不明白的地方歡迎再提問！

第一題我唔係好肯定
如果
8y-34=2y
8y－2y＝34
y=5.666667
又有可能
8y-34=10
8y-2y=10
y=5.5
(2)
y+2=3(4-y)
y+2=12-3y
y+3y=12-2
4y=10
y=2.25
