X will be ticket cost
Y is ticket agency fee
5X+y = $93
3x+y = $57
To solve, multiply the second by negative 1.
-3x-y = -$57
Then subtract the second from the first.
5X+y = $93
-3x-y = -$57
To give you 2x=$36
Divide both sides by 2 to get x=$18
If x=$18, then plug it in to get your solution for y!
5($18) +y =$93
$90+y=$93
Y=$3
3($18)+y = $57
$53 +y =$57
Y=$3
