#### Explanation:

We are looking for minimal integer solutions for:

#3n=p#

#8n=2q#

#2m=3p+q#

We can try a few values for

#3(1)=p# ...okay

#8(1)=2q rarr q=4# ...okay

#2m=3(3)+4# ...No; would require#m# to be a fraction

#3(2)=6=p# ...okay

#8(2)=2q rarr q=8# ...okay

#2m= 3(6)+8 rarr m= 13# ...okay

and we have our solution.
