I would say C because it is the only one that makes the most sense, if you reflect something from the y-axis, the negatives become positives, and the positives become negitives
This system has no solution.
x = -7y + 24 can be rewritten as x = 24 - 7y
to simplify x + 7y = 32, we have to subtract 7y from both sides
x = 32 - 7y
Now, our system is as follows:
x = 24 - 7y
x = 32 - 7y
