Question

Which of the following is not a solution to the system of linear equations below?
5y=3x+15
6=10y-30


A.
(5, 6)
B.
(–15, 12)
C.
(0, 3)
D.
(–10, –3)

Answer 1

okay, you would need to plug in each answer choice to see which one makes the equation false.

(x,y)
(5,6)
(-15,12)
(0,3)
(-10,-3)

so now you know which ones are x and which ones are y, choose one of the points and plug into the equation. if it comes out false, then that point you chose is your answer.

Answer 2

is it A ? @CloverRacer

Answer 3

no because it makes the equation true

Answer 4

it was B

Answer 5

yep. (:
