Question 970178
p, a number;


{{{21p-102}}};


{{{21p-102=p*11+8}}}, but be aware your description is ambiguous.  You should show your interpretation of the description since it may be just as good as mine, but different and give a different result. 


to solve:
{{{21p-102-11p=8}}}
{{{21p-11p=8+102}}}
{{{10p=110}}}
{{{p=11}}}--------------you must have taken the meaning to be what I did.
