Question 899540
Do you mean, "What are we"?


x and y, "You all".

xy=30 and y-x=1 and x+y=11

Three equations and two unknown variables.


{{{-x+y+(x+y)=1+11}}}
{{{2y=12}}}
{{{y=6}}}
Use this to find x.
{{{x=11-y}}}
{{{x=11-6}}}
{{{x=5}}}


Those also give {{{xy=5*6=30}}} as specified.
You may be 5 or you may be 6.
