Answer:9x6−156x5+664x4+176x3−620x2−48x+144
Step-by-step explanation:
Search the question on the internet and ask if which it is out of them both answers and there you go
Yes because it's a improper fraction
Use substitution and substitute y into the other equation. One of the equations already gives you y in terms of x, so use that and substitute it into the other equation. y = 3x - 4
Plug into the other equation: -3y = -9x + 12
-3(3x-4) = -9x + 12
-9x + 12 = -9x + 12
This is an identity. So that means that any value of x makes this equation true. So B.
