As of a certain date, there had been a total of 14,649 performances of two shows on Broadway, with 2389 more performances of Sho

Naddik [55]

Subtract the difference:

14,649 - 2389 = 12,260

Divide that by 2

12,260 / 2 = 6,130

That is the number of shows for B.

For A add the 2,389 to the number of shows for B

2389 + 6130 = 8,519

Show A = 8,519

Show B = 6,130

5x−y=3<br> −5x+2y=4<br> Which ordered pair satisfies the system of equations shown above?

ale4655 [162]

Answer:

$(2, 7)$

Step-by-step explanation:

We can solve this system of equations by using elimination.

In this case, we can eliminate x by adding the two equations:

$5x+(-5x)-y+2y=3+4\\5x-5x+y=7\\y=7$

Then, substitute 7 for y to solve for x:

$5x-y=3\\5x-7=3\\\text{Add 7 to both sides}\\5x=10\\\text{Divide both sides by 5}\\x=2$

Substitute both these values into the system to check our answer:

$5x-y=3\\5(2)-7=3\\10-7=3\\3=3\rightarrow \text{correct!}$

$-5x+2y=4\\-5(2)+2(7)=4\\-10+14=4\\4=4\rightarrow \text{correct!}$

Therefore the ordered pair is:

$(x, y)=(2, 7)$
