Answer:
230 tickets were sold at door and 170 tickets were sold in advance.
Step-by-step explanation:
Let x represent the number of tickets sold at the door.
Let y be the tickets sold in advance.
Equations form as per given scenario are:
or x=400-y ......(1)
......(2)
Substituting the value of x from (1) in (2)
=>
We get y = 170
And x = = 230
Hence, 230 tickets were sold at door and 170 tickets were sold in advance.
230 were sold at the door
170 were sold in advance
*i dont know if this is the proper way to do it but it has the correct answer
x=at door y=in advance
x+y=400
3x+2y=1030
y=-x+400
2y=-3x+1030
y=-3/2x+515
-x+400=-3/2x+515
x=230 y=170
