Which pairs are solutions to the equation?

5xy + 9 = 44

A

(1, 7) and (4, 11)

B

(4, 11) and (2, 3)

C

(1, 7) and (7, 1)

D

(7, 1) and (2, 3)

The answer is C) (1,7)and (7,1). In order to find the correct answer ,just substitute the numbers for x and y in the problem,so:5(1)(7)+9=44 .35+9 =44,44=44 ,so that's true .Then check the other set of given numbers by substituting for x and y :5(7)(1)+9=44,351=35+9= 44,therefore 44=44 ,so both sides are true.Also remember x is always the first number given,and then y.*
