Question 620558
Simply check each answer choice.



Check choice A)


x+2y=5


1+2(3)=5 ... Replace 'x' with 1 and 'y' with 3


1+6 = 5


7 = 5 ... FALSE, so (1,3) is NOT a solution

-------------------------------------------------------

Check choice B)


x-2y=5


1-2(3)=5


1 - 6 = 5


-5 = 5 ... FALSE, so (1,3) is NOT a solution

-------------------------------------------------------

Check Choice C)


2x+y=5


2(1)+3=5


2+3 = 5


5 = 5 ... TRUE, so (1,3) is a solution for 2x+y=5


So the answer is choice C)


If you can only choose one answer, then you are done. If you can choose multiple answers, then I suggest you check choice D to make sure it works or not.
