Answer:
[tex](5,-1)[/tex]
[tex](10,2)[/tex]
Step-by-step explanation:
we have
The ordered pairs that are solutions to the equation [tex]3x-5y=20[/tex] are
[tex](5,y),(x,2)[/tex]
Step 1
Substitute the value of x of the first ordered pair and solve for y in the equation
[tex]3(5)-5y=20[/tex]
[tex]5y=15-20[/tex]
[tex]y=-1[/tex]
The first ordered pair is [tex](5,-1)[/tex]
Step 2
Substitute the value of y of the second ordered pair and solve for x in the equation
[tex]3x-5(2)=20[/tex]
[tex]3x=20+10[/tex]
[tex]x=10[/tex]
The second ordered pair is [tex](10,2)[/tex]
