Which ordered pair is a solution to the equation 3x + 9y = 27 ?

Question options:

(6, 1)

(1, 8)

(1, 11)

(8, 1)

(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

the answer is 15% decrease
