TRUE OR FALSE:

Question

If a > 0, and a + b = c, then c > a by the “Three Possibilities” Property.

Answer 1

true or false, If a is greater than zero, and a + b = c, then c is greater than a

try a few specific examples

a= 2, b=3, c =5 true 5 is greater than 2

a=3 b=-5, c= -2 false -2 is not greater than 3

one counterexample makes the proposition false

to be true both a and b have to be greater than 0
