Answer:

C) 5x=5

Step-by-step explanation:

Multiplying an equation by a number means multiplying all its terms by that number.

Multiplying equation one by 2,

2(2x+y=3)

4x+2y=6

Adding that to equation 2,

4x+2y=6

+ x-2y=-1

The result is 5x=5

Mariana [72]

Answer:

<u>96 percent</u> of the seats were the tickets sold.

Step-by-step explanation:

Given:

Atlantic auditorium has 850 seats. Tickets were sold for 816 of the seats.

$\frac{816}{850}\times 100$

$=0.96\times 100$

$=96\%.$

Therefore, 96 percent of the seats were the tickets sold.
