✔ 最佳答案
3(4-P) = 2(P+3)Step 1 : Expand
12 - 3P = 2P + 6
Step 2: put all the 'Ps' to one side
12 - 6 = 2P + 3P
Step 3: Tidy and solve
6 = 5P
P = 5/6

**** I meant
6 = 5P
P = 6/5

3(4-p)=2(p+3)
12-3p=2p+6
-5p=-6
p=6/5
12-3p=2p+6
-5p=-6
p=6/5

3(4-p)=2(p+3)
12-3p=2p+6
-3p-2p=6-12
-5p=-6
p=-6/-5
p=1.2
12-3p=2p+6
-3p-2p=6-12
-5p=-6
p=-6/-5
p=1.2
