Question

Which ordered pair is the solution

Answer 1

Try plugging in the x and y values into the equation to see if both are true:

A (5,5)
2(5)+4(5)=22
10+20=22
30=22
Since this obviously does not work there is no point in plugging it into the second equation as well.
B (5,4)
2(5)+4(4)=22
10+16=22
26=22
Since this does not work either, we can move on from this one as well.
C (5,2)
2(5)+4(2)=22
10+8=22
18=22
Okay, this doesn't work either, now it's probably the last one but it's important to check to make sure
D (5,3)
2(5)+4(3)=22
10+12=22
22=22
Since this worked, put the numbers in the other equation just to make sure
6(5)+2(3)=36
30+6=36
36=36
D is the answer

Answer 2

The answer is D, the ordered pair (5,3)
