Answer: top right corner
Reason
The top left corner solves to
after subtracting 3.5 from both sides. Unfortunately m = 19 does not work here because
is false.
The top right corner has these steps when solving for m.

The inequality sign flips when multiplying or dividing both sides by a negative number.
m = 19 fits in that last inequality since
is a true statement.
Therefore, m = 19 is a solution to
