The answer is c). (x-5)(x-7)
Carmen simplifies the expression and gets the coefficient of y is 10. Thus, the correct option is C.
<h3>What is simplification?</h3>
Simplification is to make something easier to do or understand and to make something less complicated.
Given
Carmen simplifies the expression 
.
We can add x term with x, y term with y, and constant with constant.
On simplifying, we have
Thus, the coefficeint of y is 10.

Correct me if I am wrong.
I haven't done fifth/sixth grade math in a long time
et balcony tickets be represented by 'b' & main floor tickets by'm'.
There were 100 more balcony tickets than main-floor tickets sold for a concert.
-->> b-m=100...(eq. 1)
From the second condition we get...
-->> 4b+12m=3056...(eq. 2)
multiply eq1 by 12 and add it with eq.2
-->(12b-12m)+(4b+12m)=(1200+3056)
-->16b=4256
-->>b=266
so 266 balcony tickets were sold.
hope this helps
