N/2+5=3
move +5 to the other side
sign changes from +5 to -5
N/2+5-5= 3-5
N/2= -2
Mutiply both sides by 2/1
N/2*2/1 - Cross out 2 and 2 , divide by 2 then becomes N
-2(2)/1= -4/1= -4
N= -4
Answer : N= -4
Answer:

Step-by-step explanation:
Keywords:
System of equations, variables, cost, tickets, adults, children.
For this case we must solve a system of equations with two variables represented by the tickets of students and adults of a school production.
We define the variables according to the given table:
a: Number of tickets sold to adults
c: Amount of tickets sold to children.
We then have the following system of equations:
A + c = 67
10a + 5c =440
From the first equation, we clear the value of the variable c:
C = 67 - a
Answer:
The value that could replace c in the table is:
C = 67 - a
Option C is the answer!
