Label the statement as "true" or "false". If "false", correct the underlined portion. Or in this case since I can't underline text, the second inequality.

So if it's false, what part of the second inequality needs to be changed to make it true?

if y-x

So if it's false, what part of the second inequality needs to be changed to make it true? 

if y-x<5-x, then y<5.   y<5 is underlined

We need to start with the "if" part and see if we can transform it into the "then" part.

jtvatsim · Answer

So, let's examine y - x < 5 - x

jtvatsim · Answer

Can we simplify this at all?

jtvatsim · Answer

For instance, is there a way to remove the x's?

jtvatsim · Answer

Let me know what you think, then we'll proceed. :)

anonymous · Answer

yes i could add the x's on each side

jtvatsim · Answer

exactly, and what does that leave you with?

anonymous · Answer

the same equation as the second one

jtvatsim · Answer

Yep, so since we started with the "if" statement and transformed it into the "then" statement, we have proved that it is TRUE! :D
