Question

{ 5（m-1)=2(n+3) { 2(m+1)=3(n-3) 要过程哦！谢谢

Answer 1

这是啥哦，我初中毕业呢。看这样的行不行哈
5（m-1)=2(n+3) 2(m+1)=3(n-3) 同理5（m-1)=2(n+3) 2(m+1)=3(n-3)
5m-5=2n+6 2m+2=3n-9 2n=5m-11 3n=2m+11
5m=2n+6+5 2m=3n-9-2 n=(5m-11)/2 n=(2m+11)/3
m=(2n+11)/5 m=(3n-11)/2 (5m-11)/2=(2m+11)/3
(2n+11)/5=(3n-11)/2 15m-33=4m+22
15n-4n=22+55 11m=55
11n=77 m=5
n=7
搞定m=5 n=7

Answer 2

{ 5（m-1)=2(n+3) 5m-5=2n+6 5m-2n=11 15m-6n=33

{ 2(m+1)=3(n-3) 2m+2=3n-9 2m-3n=-11 4m-6n=-22 11m=55，m=5，n=7
