The sum of x and y is not 10.
OpenStudy (anonymous):
\[\large x+y=10\] ?
OpenStudy (anonymous):
is that what you meant to type? If so, what does 'negation' mean to you? Hint: what are the first 3 letters of that word and what do they remind you of?
OpenStudy (anonymous):
negtive so is it x-y not equal to 10
OpenStudy (anonymous):
No..
See the example:
If your age is 21 years then you are mature..
If your age is not 21 years then you are not mature..

We only need to change one thing to negate this statement.

Oh my last reply was to your question of "do you always change that".
I recommend closing this question and then starting a new one for your new question. :D
