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)
