The amount received by me = $ x .
We are given " the amount she recives is 11 more than my amount" .
The amount of my friend's allowance is taken by the variavle y .
Therefore, we can repharse the given statement as :
" My friend's allowance y is 11 more than my allownace x" .
Now, we can seup an equation as:
y = 11 more than x.
Or
For " more than " pharase we would put a plus sign.
Therefore, y= x+11 is the final eqaution.
