xp=17%28pqr%2F42%29%2Bam%2B13p looks complicated, but let's look at the right side piece by piece:
system%28p=29%2F13%2Cr=42%2Fp%2Cq=100%29--->system%28pr=p%2842%2Fp%29=42%2Cq=100%29--->pqr=42%2A100--->pqr%2F42=42%2A100%2F42=100
m=38%2Fa--->am=a%2838%2Fa%29=38
p=29%2F13--->13p=13%2829%2F13%29=29
So, with p=29%2F13---> xp=%2829%2F13%29x , and all of the above, we get
%2829%2F13%29x=17%2A100%2B38%2B29
%2829%2F13%29x=1767
%2813%2F29%29%2829%2F13%29x=%2813%2F29%291767
x=%2813%2F29%291767=22971%2F29
It would be great if I could simplify this, but 1767=3%2A19%2A31
