Answer:
Moses got into the elevator at the 8th floor.
Step-by-step explanation:
Let's call the floor which Moses started at x. Going down decreases the floor number and going up increases the floor number. We then form the equation [tex]x-5+6-7=2[/tex] which is the same as [tex]x-8=0[/tex] which means [tex]x=8[/tex]. Moses got in at the 8th floor.
