Question 569235
x < y ... Start with the given inequality.


x - x < y - x ... Subtract x from both sides


0 < y - x ... Subtract x-x to get 0x or 0


0-y < y - x - y ... Subtract y from both sides


-y < -x ... Simplify 0-y to get -y and subtract y-y to get 0y or 0 (and that goes away)




So this shows us that if x < y, then -y < -x
