The box office center of a football stadium sold 78 tickets less than the all other box offices. how many tickets were sold by the box office center, if the total number of tickets sold was 520?

520/2=260 (Assuming there's only two box offices)

260-78=182

182 tickets sold by box office

221 tickets were sold by the box office center

Step-by-step explanation:

x: other box offices

x-78: box office center

total: 520 tickets

x+x-78=520

2x-78=520

+78          +78

2x=299

/2             /2

x=299

299 is the how many tickets the other box offices sold

so the amount of tickets the box office center sold should be

299-78

221

do you mean add both of the equations together

because if you do the answer is 10x-5
