Answer: F
Step-by-step explanation:
- This does not have infinitely many solutions (adding the equations, we get a fixed value of x)
- This has no solutions (the left hand sides are the same but the right hand sides have different values)
- This has one solution (the first equation givess a fixed value for x)
- This has no solutions (same reason as 2)
- This has one solution (same reason as 3, just the second equation instead of the first)
- This has infinitely many solutions (multiplying both sides of the top equation by -2 gives the bottom equation).
(-12 - 8)/(6 - 8) = -20/-2 = 10.
It's positive.
