For this system, is the ordered pair a solution of both equations?How do you know?
No, it is not because when you plug in x for the first equation you get -1 as y, not 1. And for the second equation when you plug in 5 for x you get -1 again, not 1.
aight the first thing u do is sub in the coordinates for x and y
so in the first equation ur x will be 5 and y will 1
then u solve the problem and both sides should be equal
so ur equation should look like this
1=9- as u can see both sides don't equal the same ( so it doesnt work for the first one, from there u have answered the question since it says doesn it work for BOTH solution and it doesnt)
but for practice u should try the second one
1=-1( as u can see it doesnt work for this one either, so now u have ur answer that no it doesnt work)
p.s- a solution that would work would be something like this
cuz when u sub the x and the y they both equal 1
