✔ 最佳答案

1. (p/3) + 16 = 8(q/2 + 1)
(48 + p) / 3 = 4q + 8
48 + p = (4q + 8)3
48 + p = 12q + 24
48 - 24 + p = 12q
24 + p = 12q
(24 + p)/12 = q
q = 2 + (p/12)

2. 3p = (m/n) + (2/m)
3p = m² + 2n
3p - m² = 2n
n = (3p - m²)/2

I only know 1
1)..p.................q..........
(------)+ 16 =8(-------- + 1)
.....3..................2..........
....p................q..+... 2
(--------)+16=8(-------------)
....3....................2
.16p....8q+16
------=-----------
...3.........2
2(16p)=3(8q +16)
32p=24q+48

1 (p/3) +16=8(q/2 +1)
(p/3)+16= 4q+8
4q=(p/3)+8
q= (p/12)+2
=(p+24)/12

2 31=(m/n)+(2/m)
31-(2/m)=m/n
n=m/[31-(2/m)]
=m/[(31m-2)/m]
m²/(31m-2)
