n = number

n < 3000

n = 32( p) + 30

n = 58( q) + 44

32( p ) + 30 = 58 ( q) + 44

3000 - 30 = 32p

P = 92     n = 2944

2944 - 44 = 58 q     q = 50

n = 2944

2944 does not work!

Let x be the number, all the other letters positive integers
x=32n+30
x=58m+44
32n+30=58m+44 and so
16n+15=29m+22
16n=29m+7
16n=16m+13m+7, so we need to find am m for which 13m+7 is divisible by 16.
Trial and error, I confess.  m=13 gives 169+7=176=16×11
x=58×13+44=798=32*24+30

What you know:

x<3000
X>32
x>58

(45x58) + 44 =2654

2654/32= 82 R30

How did u know to use 45

n/32 = Q + 30/32 => n = 32Q + 30
n/58 = P + 44/58 => n = 58P + 44 => n mod 58 = 44

Using an Excel SS (below) I found three numbers:

798, 1726, and 2654

But I don’t know how to do it otherwise; someone help!

Q n=32*Q+30 n mod 58 = 44?
