Answer:

(8,8)

Step-by-step explanation:

The first equation says y and x are the same, so any x in the second equation can be replaced with a y, so

y = 2x - 8 and y = x, substituting x for y gives

x = 2x -8, subtract x from each side, add 8 to each side, get

8 = x

substitute that value back into the first equation

y = x, x= 8, so y=8

At the movie theatre, child admission is $6.30 and adult admission is $9.60 . On saturday, twice as many adult tickets as child

joja [24]

Let's assume

number of child tickets sold on saturday is x

number of adult tickets sold on saturday is y

On saturday, twice as many adult tickets as child tickets were sold

so, we get

$y=2x$

child admission is $6.30 and adult admission is $9.60

a total sales of $535.50

we get

$6.30x+9.60y=535.50$

now, we can plug y=2x

$6.30x+9.60*2x=535.50$

now, we can solve for x

$25.5x=535.5$

$x=21$

now, we can find y

$y=2*21$

$y=42$

so,

number of child tickets sold on saturday is 21

number of adult tickets sold on saturday is 42.........Answer
