Answer:
218 students purchased tickets at the dance.
Step-by-step explanation:
Let,
x be the number of presale tickets
y be the number of tickets sold at the dance
According to given statement;
x+y=334 Eqn 1
18x+24y=7320 Eqn 2
Multiplying Eqn 1 by 18
18(x+y=334)
18x+18y=6012 Eqn 3
Subtracting Eqn 3 from Eqn 2
(18x+24y)-(18x+18y)=7320-6012
18x+24y-18x-18y=1308
6y=1308

Therefore,
218 students purchased tickets at the dance.
70 pieces
7/10 = x/100
10*10=100
7*10 = 70
70/100

Let's go:

Solution #1:
x - 3 = 5
x = 5 + 3
x = 8
Solution #2:
x - 3 = - 5
x = - 5 + 3
x = - 2
