The image is really unclear but I will assume that the number of teams given = 66
and the formula is
n = \frac{ {t }^{2} - t }{2}
plug in the number of teams
66 = \frac{ {t}^{2} - t }{2}
multiply both sides by two
132 = {t}^{2} - t
subtract 132 from both sides and factor
t = 12

What is the solution to the system of equations? -2x + y = -5 3x – 2y = 12 A) (3, 1) B) (6, 3) C) (-2, -9) D) (-2, -1)
max2010maxim [7]

Answer:

The correct answer is D) (-2, -1)

Step-by-step explanation:

In order to solve this system of equations, start by multiplying the entire first equation by 2. Then add the two equations together. This will get the y's to cancel and allow you to solve for x.

-4x + 2y = -10

3x - 2y = 12

---------------------

-x = 2

x = -2

Now that we have the value for x, we can find y by plugging the x value into either equation.

-2x + y = -5

-2(2) + y = -5

-4 + y = -5

y = -1
