Doing a test can somebody help me with this X=-9+9

0

Step-by-step explanation:

You take -9 and add 9 and it becomes 0.

0

Step-by-step explanation:

x = - 9 + 9

= 0

(If you owe 9 apples to your friend, and he gives you 9 apples, how much do you owe him now? 0, because you can give him back the 9 apples and you will owe him nothing else.)

(Or you can just rewrite the equation as x = + 9 - 9

= 0

because 9 minus 9 is 0.)
