Question

Please help, Which ordered pairs in the form (x, y) are solutions to the equation 3x−4y=21?

Select each correct answer.
(−1, −6)
(−3, 3)
(7, 0)
(11, 3)

Answer 1

(-1,-6) and (7,0) and (11,3)

Explanation:

Just replace the x,y valuesin the equation

3x - 4y = 21

3(-1) - 4(-6) simplified to -3 - (-24) = 21 yes!

3x - 4y = 21

3(-3) - 4(3) simplified to -9 - 12 = -21 no

3x - 4y = 21

3(7) - 4(0) simplified 21 - 0 = 21 yes!

3x - 4y = 21

3(11) - 4(3) simplified 33 - 12 = 21 yes!
