Answer: 2
Step-by-step explanation:
Answer: 210 advanced tickets were sold. 130 same day tickets were sold.
Step-by-step explanation:
x= advanced tickets y=same day tickets
2x+3y=810 this equation represents the money
x+y=340 this equation represents the total number of tickets
x+y=340
<u>-x -x</u>
y=-340-x 2x+3(340-x)=810 210+y=340
2x+1020-3x=810 <u> -210 -210 </u>
-x+1020=810 y=130
<u> -1020 -1020</u>
<u>-x</u>=-<u>210</u>
-1 -1
x=210
