Complete the ordered pair (15, ) for the equation x - 5y = -25

This is quite straightforwatrd.

x is 15, so

15 - 5*y = -25

so what is y?

If x = 15, substitute that value in the equation and solve for y.

To find the missing value in the ordered pair (15, ), we need to substitute the given x-coordinate, 15, into the equation x - 5y = -25.

Let's plug in x = 15:

15 - 5y = -25

Now, we can solve for y:

-5y = -25 - 15

-5y = -40

Divide both sides of the equation by -5:

y = -40 / -5

y = 8

Therefore, the complete ordered pair is (15, 8).
