Answer:
(6, 1 )
Step-by-step explanation:
To determine which ordered pair is a solution
Substitute the x and y values into the left side of the equation and if equal to the right side then it is a solution.
(6, 1 )
3(6) + 9(1) = 18 + 9 = 27 ← Solution
(1, 8 )
3(1) + 9(8) = 3 + 72 = 75 ≠ 27
(1, 11 )
3(1) + 9(11) = 3 + 99 = 102 ≠ 27
(8, 1 )
3(8) + 9(1) = 24 + 9 = 33 ≠ 27
Then (6, 1 ) is a solution to the equation
