Let x be the price of senior tickets
Let y be the price of student tickets
Day 1. 3x+12y=$213.00
Day 2. 5x+2y=$85.00 Take day 2 equation and multiply all by 6 so that
Day 2. 30x+12y=$510.00 now subtract Day 1 equation
Day 1 -3x-12y=-213.00 getting
27x = 297 divide by 27 getting x=$11.00
Senior tickets cost $11.00 substitute in day 1 and find y the students ticket cost
33.00 +12y =213.00 subtract 33 from both sides
12y=213.00-33=180.00 divide by 12
y=$15.00 Students ticket cost $15.00 each.
Day 2 equation was multiplied by 6 for the sole reason of getting the y variable to equal 12, so when subtracted from day 1 equation the y value would drop out leaving only x so it could be solved.
