therefore
6X+7Y=50
6X+6Y+Y=50
6(X+Y)=50-Y
So 50-Y must be a multiple of 6.
And 7Y
《
50
y \u
50/7(7 and 1/7)
Because y is a natural number, y can only be 0-7.
50-Y is a multiple of 6. 0-7, only 2 matches.
So Y=2
7Y= 14
So 6X=50-7Y=36 (qualified)
So it is divided into
36、 14
60 The same practice:
Suppose one number is 6X and the other number is 7y (both x and y are natural numbers).
therefore
6X+7Y=60
6X+6Y+Y=60
6(X+Y)=60-Y
So 60-Y must be a multiple of 6.
And 7Y
《
60
y \u
60/7(8 4/7)
Because y is a natural number, y can only be 0-8.
And 60-Y is a multiple of 6, and out of 0-8, only 6 matches.
So Y=6
7Y=42
So 6X=60-7Y= 18 (qualified)
So it is divided into
18、42
