Answer: A and B

Explanation: I’ll use A as an example. When you multiply the bottom equation by -3/2, the equation becomes: -9x+6y=-3. Then, proceed to add the equations. Look at X and Y in both equations: do the Y variables in both equations equal to 0 when added together? Yes, because -6y+6y=0! Therefore, you can eliminate y in these two equations.

Hope that’s helps シ

Well you do 57 time 7 and get 399 and then it says how far will she have driven so you would add the 60 and get 459 miles.
