Question 1047948
{{{xp=17(pqr/42)+am+13p}}} looks complicated, but let's look at the right side piece by piece:
{{{system(p=29/13,r=42/p,q=100)}}}--->{{{system(pr=p(42/p)=42,q=100)}}}--->{{{pqr=42*100}}}--->{{{pqr/42=42*100/42=100}}}
{{{m=38/a}}}--->{{{am=a(38/a)=38}}}
{{{p=29/13}}}--->{{{13p=13(29/13)=29}}}
So, with {{{p=29/13}}}---> {{{xp=(29/13)x}}} , and all of the above, we get
{{{(29/13)x=17*100+38+29}}}
{{{(29/13)x=1767}}}
{{{(13/29)(29/13)x=(13/29)1767}}}
{{{x=(13/29)1767=22971/29}}}
It would be great if I could simplify this, but {{{1767=3*19*31}}}
