Which ordered pairs in the form (x, y) (x, y) are solutions to the equation 3x-4y=213x-4y=21? select each correct answer. (11, 3) (11, 3) (-1, - 6) (-1, - 6) (-3, 3) (-3, 3) (7, 0) ?

3x - 4y = 21

Its just a matter of subbing in ur answer choices to see which ones make this equation true.

(11,3)

3 (11) - 4 (3) = 21

33 - 12 = 21

21 = 21 (correct)

(-1,-6)

3 (-1) - 4 (-6) = 21

-3 + 24 = 21

21 = 21 (correct)

(7,0)

3 (7) - 4 (0) = 21

21 = 0 = 21

21 = 21 (correct)

so ur answer is : (11,3), (-1,-6), (7,0)
