Can you think of what to do next?

Answer 4

i got logged out and it changed the question on me. lol

Answer 5

7x - 5y = 28

1) (-6,-14)...x = -6 and y = -14
now we sub
7(-6) - 5(-14) = 28
-42 + 70 = 28
28 = 28 (correct) --- this one is a solution

2) (-1, -7)...x = -1 and y = -7
now we sub
7(-1) - 5(-7) = 28
-7 + 35 = 28
28 = 28 (correct) -- this one works as well
