=3500x + 15y [multiplying the equation by 100]
= 700x + 3y [dividing the equation by 5]

Total amount of tickets is 48
Step-by-step explanation:
<u>Step 1: Determine the amount of tickets they solid in all</u>
We see that the movie theater has a ratio of 4 adult tickets for every children ticket which means that wen a child purchases a ticket there are 2 adult tickets that come along.

16 children tickets
<em>Total tickets: </em> 32 adult tickets + 16 children tickets = 48 tickets
Answer: Total amount of tickets is 48
Eliminate x's by adding te 2 equations
add them
-2x+15y=24
<u>2x+9y=24 +</u>
0x+24y=48
24y=48
divide both sides by 24
y=2
sub back
2x+9y=24
2x+9(2)=24
2x+18=24
minus 18 both sides
2x=6
divide 2
x=3
x=3
y=2
(x,y)
(3,2)
