Answer:

The values that create ordered pairs that are solutions to the equation :

3x - 5y = 20.

(5,y)  = (5,-1)

(x,2)  = (15,2)

Step-by-step explanation:

Given :

3x - 5y = 20

(5,y)

Put x = 5, y = y in the given equation:

[tex]3\times 5 - 5y = 20[/tex]

[tex]-5y=20-15[/tex]

[tex]-5=5y[/tex]

[tex]y=-1[/tex]

(5,y)  = (5,-1)

(x,2)

Put x = x, y = 2 in the given equation:

[tex]3x - 5y = 20[/tex]

[tex]3x-5\times 5=20[/tex]

[tex]3x=20+25[/tex]

[tex]3x=45[/tex]

x = 15

(x,2)  = (15,2)
