回答 (10)
✔ 最佳答案
7K-(9K-16)=14-(19-K)
7K-9K+16=14-19+K
-2K+16=-5+K
-2K-K=-5+-16
-3K=-21
K=7
參考: Hope can help u ....^^
7K-(9K-16)=14-(19-K)
7K-9K+16=14-19+K
-2K+16= - 5+K
16+5=K+2K
21=3K
K=7
7K-(9K-16)=14-(19-K)
7k - 9k + 16 = 14 - 19 + k
-2k + 16 = -5 + k
-2k - k = -5 - 16
- 3 k = - 21
k = 7
7K-(9K-16)=14-(19-K)
7K-9K+16=14-19+K
-2K+16= - 5+K
16+5=K+2K
21=3K
K=7
參考: me>.
7k-(9k-16)=14-(19-k)
7k-9k+16=14-19+k
-2k+16=-5+k <-----移項 將同類的放在同一邊
-2k-k=-5-16
-3k=-21
k=7
7K-(9K-16)=14-(19-K)
7K-9K+16=14-19+K
-2K+16= - 5+K
16+5=K+2K
21=3K
K=7
7K-(9K-16)=14-(19-K)
7K-9K+16=14-19+K
-2K+16=-5+K
-2K+16-K-16=-5+K-K-16
-3K=-21
K=7
7K-(9K-16)=14-(19-K)
7K-9K+16=14-19+K
-3K=-21
K=-21/-3
K=7
7K - (9K - 16) = 14 - (19 - K)
7K - 9K + 16 = 14 - 19 + K
- 2K + 16 = K - 5
3K = 21
K = 7
參考: giroro
7K - (9K - 16) = 14 - (19 - K)
7K - 9K + 16 = 14 - 19 + K
- 2K + 16 = K - 5
3K = 21
K = 7
