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=44,35*1=35+9= 44,therefore 44=44 ,so both sides are true.*Also remember x is always the first number given,and then y.*
