✔ 最佳答案
3p + 9 - 2p - p - 5p= 3p - 2p - p - 5p + 9
= p - p - 5p + 9
= -5p + 9

3p+9-2p-p-5p
=> -5p+9
However, if u want to solve p,
3p+9-2p-p-5p= 0
=> -5p+9= 0
=> -5p= -9
=> p= -9-(-5)
=> p= -9+5
=>p= -4
=> -5p+9
However, if u want to solve p,
3p+9-2p-p-5p= 0
=> -5p+9= 0
=> -5p= -9
=> p= -9-(-5)
=> p= -9+5
=>p= -4

separate the "p" terms from the "non-p" terms:
3p+9-2p-p-5p = 9 + (3p -2p - p -5p)
now, treat the "p's" like numbers:
(3p -2p - p -5p) = p(3 - 2 - 1 - 5) = p(-5)
finally add everything together:
3p+9-2p-p-5p = 9 -5p
3p+9-2p-p-5p = 9 + (3p -2p - p -5p)
now, treat the "p's" like numbers:
(3p -2p - p -5p) = p(3 - 2 - 1 - 5) = p(-5)
finally add everything together:
3p+9-2p-p-5p = 9 -5p
