✔ 最佳答案
p/3+11=4(p/2+1) 把主項變換為q
你有否打錯左呢，either p nor q
p/3+11=2p+4
p+33=6p+12
21=5p
p=21/5
參考: 希望幫到你

把主項變換為p
P/3+11=4(p/2+1)
p/3+11=2p+4
7=2p-p/3
7=(2-1/3)p
7=5/6p
42=5p
p=42/5
p=8 2/5
P/3+11=4(p/2+1)
p/3+11=2p+4
7=2p-p/3
7=(2-1/3)p
7=5/6p
42=5p
p=42/5
p=8 2/5

p/3 + 11 = 4 (p/2 + 1)
p/3 + 11 = 2p + 4
3 (p/3 + 11) = 3 (2p + 4)
p + 33 = 6p +12
33 - 12 = 6p - p
5p = 21
p = 4 1/5
p/3 + 11 = 2p + 4
3 (p/3 + 11) = 3 (2p + 4)
p + 33 = 6p +12
33 - 12 = 6p - p
5p = 21
p = 4 1/5
2007-12-17 7:00 pm
p/3+11=4(p/2+1)
=> 6(p/3+11)=6(4(p/2+1))
=> 2p+66 = 12p+24
=> 66 - 24 = 12p - 2p
=> 42 = 10p
=> p = 4.2
=> 6(p/3+11)=6(4(p/2+1))
=> 2p+66 = 12p+24
=> 66 - 24 = 12p - 2p
=> 42 = 10p
=> p = 4.2
